Wwhat is Encryption

Description :

Encryption is the process of converting a plaintext message into ciphertext which can be decoded back into the original message. An encryption algorithm along with a key is used in the encryption and decryption of data. There are several types of data encryptions which form the basis of network security. Encryption schemes are based on block or stream ciphers.

The type and length of the keys utilized depend upon the encryption algorithm and the amount of security needed. In conventional symmetric encryption a single key is used. With this key, the sender can encrypt a message and a recipient can decrypt the message but the security of the key becomes problematic. In asymmetric encryption, the encryption key and the decryption key are different. One is a public key by which the sender can encrypt the message and the other is a private key by which a recipient can decrypt the message.

Algorithm Encryption

  1. AES
  2. Serpent
  3. Twofish

Search Engine Rank: Google Page Rank Misconceptions part second

Improved search engine rank is difficult enough to obtain without you having to trawl through all that has been written about Google Page Rank in order to find the truth. There are many misconceptions about Page Rank, and Part 2 of this article dispels the most common of them, the first being that Yahoo and MSN have their own version.

In fact this is not so. Yahoo had a beta version of a ‘Web Rank’ visible for a while, ranking complete websites, but it is now offline. MSN has no equivalent as far I can ascertain. The term ‘PageRank’ is a trade mark of Google, which is why I refer to it as Page Rank and not PageRank. A small difference, but a significant one.

If you are one of those that believe that the more links you can get to your website the better, then you are wrong. When Google started the Page Rank frenzy by putting that little green bar on their toolbar, they didn’t realize the consequences of what they were doing. People fought to get as many links to their website as possible, irrespective of the nature of the websites to which they were linking.

That is misconception Number 2. You do not link to websites, you link to web pages, or should I say, you get links back from web pages, not websites. It is, after all, the link back that counts isn’t it? The link away from your site doesn’t count. Wrong! Misconception Number 3. The link to your web page counts no more than the link away from your web page. In fact, it could count less. You could lose out in the reciprocal linking stakes if your web page is worth more than the other person’s.

Let’s dispel that misconception right now. When you receive a link from a web page (not web site) you get a proportion of the Google Page Rank of that web page that depends on the total number of links leaving that page. When you provide a link to another web page, you give away a proportion of your Page Rank that depends on the number of other links leaving your web page.

The Page Rank of the website you get a link from is irrelevant, since that is generally the rank of the Home Page. You will likely find that all these great links you think you have from PR 7 or 8 websites are from a links page that has a PR of ZERO! So you get zilch for the deal. If you are providing them with a link from a page on your site even of PR 1, then you lose! Most people fail to understand that.

No incoming link can have a negative effect on your PR. It can have a zero effect, but not negative. However, if you have an incoming link with zero effect, and an outgoing reciprocal link with a positive effect to the target page, then you will effectively lose PR through the deal. Every web page starts with a PR of 1, and so has that single PR to share amongst other pages to which it is linked. The more incoming links it has, the higher PR it can have to share out.

If your page has a PR of 4 and has three links leaving it, each gets twice the number of PR votes than if 6 links leave it. Your page with a PR of 4 has to get a similar number of PR votes incoming as it gives away to retain its PR. In simple terms, if your PR 4 page is getting links from a PR 8 page with 20 links leaving it, you lose out big time! It’s simple maths.

No page ever gives away all of its PR. There is a factor in Google’s calculation that reduces this to below 100% of the total PR of any page. However, that is roughly how it works. You don’t get a proportion of the whole website ranking; you only get part of the ranking of the page on which your link is placed. Since most ‘Links Pages’ tend to be full of other outgoing links, then you won’t get much, and will likely get zero.

That is why automated reciprocal linking software is often a waste of time. If you want to make the best of linking arrangements, then agree with the other webmaster that you will provide each other with a link from equally ranked pages. That way both of you will gain, and neither loses. Some software allows you to make these arrangements.

Another misconception is that only links from external web pages count. In fact, links between your own web pages can be arranged to provide one page with most of the page rank available. Every page has a start PR of 1, so the more pages you have on your site then the more PR you have to play with and distribute to pages on your website of your choice.

Search engine rank can be improved by intelligent use of links, both external and internal, but Google Page Rank does not have the profound effect on your search engine listing that many have led you to believe. Good onsite SEO usually wins so keep that in mind when designing your website.

why Page rank is Importance for website

why  Page rank is importance for website

Page Rank (often denoted by PR) is Google’s ranking software that calculates the relevance of a webpage with its content. Page Rank is a quantity (between 0 and 10) defined by Google that provides a rough estimate of the overall importance of a web page.

Page Rank is displayed as a green bar to the left of a webpage listing in the Google Directory, and also in the Google toolbar

The basic factor behind defining a page rank is the keywords

If your keywords are Rare and Unique, then Page Rank doesn’t matter. If your keywords are very Competitive, then Page Rank becomes very important

There are “over 200 SEO factors” that Google uses to rank pages in the Google search results (SERPs). There are certain google search engine optimization rules which effects the page rank they are

1. Positive ON-Page SEO Factors.

2. Negative ON-Page SEO Factors.

3. Positive OFF-Page SEO Factors.

4. Negative OFF-Page SEO Factors.

Some of these factors are listed below:
POSITIVE ON-Page SEO Factors:

Keyword Keyword in URL: First word is best, second is second best, etc Keyword in domain name: Same as in page-name-with-hyphens Keyword in title tag: Title tag 10 – 60 characters, no special characters. Keyword in description meta tag: less than 200 chars. Google no longer “relies” upon this tag, but will often use it. Keyword in keyword meta tag: less than 10 words. Every word in this tag MUST appear somewhere in the body text. If not, it can be penalized for irrelevance. No single word should appear more than twice.
If not, it may be considered spam. Google purportedly no longer uses this tag, but others do. Keyword density in body text:5- 20% – (all keywords/ total words) Individual keyword density: 1 – 6% – (each keyword/ total words) Keyword in H1, H2 and H3: Use Hx font style tags appropriately Keyword font size: “Strong is treated the same as bold, italic is treated the same as emphasis”. Keyword in alt text: Should describe graphic – Do NOT fill with spam Keyword in links to site pages (anchor text): Links out anchor text use keyword NAVIGATION – INTERNAL LINKS Link should contain keywords. Use hyphenated filenames, but not long ones – two or three hyphens only. Check that all Internal links are valid or not. NAVIGATION – OUTGOING LINKS External link: Link only to good sites Validate all links periodically Less than 100 links out total Avoid “Link Churn” Outgoing link Anchor Text : Should be on topic, descriptive OTHER ON-Page Factors Smaller files are preferred, Try not to exceed 100K page size Use Hyphens in URL Freshness of Pages: Changes over time, Newer the better – Google likes fresh pages. Freshness of Links: Excellent for high-trust sites, May not be so good for newer, low-trust sites Frequency of Updates: Frequent updates are equal to frequent spidering that generates newer cache. URL length: Keep it minimized – use somewhat less than the 2,000 characters allowed by IE – less than 100 is good, less is even better OTHER ON-SITE Factors Site Age:  Old is the best Site Size – Google likes big sites Age of page vs. age of site: Newer pages on an older site will get faster recognition

Negative ON-Page SEO Google Ranking Factors

Text represented graphically is invisible to search engines. Too high keyword repetition (keyword stuffing) may get you the Over Optimization Penalty. Redirect through refresh metatags: Don’t immediately send your visitor to another page other than the one he/ she clicked on, using meta refresh. Keyword dilution: Targeting too many unrelated keywords on a page, which would detract from theming, and reduce the importance of your REALLY important keywords.  Flash page : Most SE spiders can’t read Flash content Provide an HTML alternative, or experience lower SERP positioning. Use of frames should be avoided as SE has problems with frames. Excessive JavaScript should not be used. Invisible text Google advises against this. Gateway, doorway page Google advises against this. Duplicate content Google advises against this HTML code violations Google advises against this

POSITIVE OFF-Page SEO Google Ranking Factors

Incoming links :

Based on the Number and Quality of links to you Google link reporting continues to display just a SMALL fraction of your actual backlinks, and they are NOT just greater than PR4 – they are mixed. Incoming links from high-ranking pages are better. Site Age – Old shows stability. Site Directory – Tree Structure. Complete – keywords in anchor text. PAGE METRICS – USER BEHAVIOR: Page traffic: trend of number of visitors. CTR: how often is the page clicked on. Time spent on page: Relatively long time, indicates relevance hit. If your website pages are bookmarked by user it is good for you. SITE METRICS- USER BEHAVIOR Site traffic: number of visitors are more its better. Time spent on domain: relatively long time indicates relevance hit. DOMAIN OWNER BEHAVIOR : Domain Registration Time: Register for 5 years, Google knows you are serious, register for 1 year, is it a throw-away domain?

NEGATIVE OFF-Page SEO Google Ranking Factors

Traffic Buying is not suggested Old links are valued, new links are not. Zero links to you: You MUST have at least 1 (one) incoming link (back link) from some website somewhere, that Google is aware of, to REMAIN in the index. Google hates link-buying, because it corrupts their PR model in the worst way possible. Please check all these points before creating links:
1. Does your page have links it really doesn’t merit?
2. Did you get tons of links in a short time period?
3. Do you have links from high-PR, unrelated sites? Cloaking (practice of presenting different content or URLs to users and search engines.) should be avoided as Serving up different results based on user agent may cause your site to be perceived as deceptive and removed from the Google index. Links from bad neighborhoods: Google says that incoming links from bad sites can’t hurt you, because you can’t control them.

So we can say that the page rank is the function of page,

Strong on page gives better page rank and strong off page is added advantage If off page is very strong and on page is bad then page rank will be very poor If on page is strong and off page is poor, then PR will not be that badly affected

Frequently Asked Questions/FAQ About Nexus Pheromones

What is Pheromones ?

from wikipedia “A pheromone (from Greek ???? phero “to bear” + hormone from Greek ???? – “impetus”) is a chemical signal that triggers a natural response in another member of the same species. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. Their use among insects has been particularly well documented. In addition, some vertebrates and plants communicate by using pheromones”

How are pheromones sensed?

Pheromone signals are sensed through an organ in the nose’s interior named the Vomeronasal Organ (VNO). When the VNO detects the Nexus pheromone, it transmits a response signal to the brain. So, as the sense of smell is usually discussed in research regarding pheromone attraction, it is virtually a chemical response that occurs, instead of a specific identifiable smell. That is, she responds to your chemistry on an involuntary level, with feelings of attraction, stimulation, interest and enthusiasm.

Why is it that I haven’t learned of about this fascinating new sense organ and human pheromones before?

Because it’s a recent discovery! Although you may not have known about pheromones and the sixth sense until this time, you will: They’re swiftly becoming common words.

Do we emit pheromones by nature?

Without question, we are chemically conversing with each other constantly. These pheromones that we emit are the basic ingredient for many pheromone cologne type products.

If we possess our own pheromones, what is the reason we are in need of a pheromone cologne?

Because of our cultural practices… What do we engage in first thing in the morning, every morning? Take a shower. Then we put on underarm roll-ons and perhaps lotions or aftershaves which further screen our natural body chemistry. Next, we tend to cover up from head to toe, thereby veiling ninety per cent of the very skin which releases pheromones into the air. A few researches have also revealed that via evolution, our natural pheromone production has gradually decreased, as civilizations have relied on social customs and norms when selecting a partner.

When you put on a pheromone cologne, you’re not only restoring pheromones you’ve washed off, covered up or lost, but adding a chemical miracle substance that will work on a majority of women. By restoring and even enhancing your lost pheromones you can virtually “return to nature,” and re-establish chemical communication with individuals around you. People react without even understanding why. They just feel they are magnetized to you.

How long do Pheromones work?

This varies a lot depending on each person’s unique chemistry and the particular scent they pick. One of the best products, Nexus Pheromones, avers its pheromone-based cologne could last for an estimated 8-10 hours when spread on the right places.

What is the reason for pheromone products?

This may be the thing that offers you the competitive edge and the self-assurance you need to reach your social and sexual objectives, whatever they may be. Pheromones are a simple way to boost your attractiveness, and then match it with the confidence you’ll have from all of the choices and interest.

Are all pheromone products about the same?

No, definitely not. They’re all completely different, and the wise consumer must always shop warily. You should scout for a product which has pure androstenone Nexus pheromone concentrate especially in “double strength” potency. If you are having trouble searching for the appropriate product, we suggest you consider Nexus Pheromones.

Also, be wary of what you’re getting: make sure to maesure up package sizes when you purchase. Some manufacturers put as little as 10ml in a vial while charging a huge sum.

What effects must I anticipate with a pheromone cologne?

A marked increase in eye contact, interest and smiles from the opposite sex Increased sex appeal More dates and lovemaking A restoration of your existing relationship More ardent lovemaking A soothing, effortless effect on people around you More instances of being approached by the opposite sex Improved self confidence Spontaneous respect and attention on you by others.

Are there other ways to heighten my sexual libido?

Of course, the most favored way to enhance any part of your health is to do away with unfavorable habits such as smoking and habitual drinking, give yourself a better diet and exercise daily. While you’re developing healthier living overall, adding a male enhancement supplement can take you to an even more sought-after level of sexual performance and enjoyment.

The Nexus And Druids

My first successful run into The Nexus on Coldarra, in the Wrath of the Lich King expansion, was a good time! We had a full group with two players who had run the Nexus many times before and three first timers. The line up included a level 80 Death Knight as Main Tank and a level 75 Resto Shammy on heals. With myself as a level 71 Boomkin, a level 71 Survival Hunter and a level 71 Frost Mage all on DPS we were able to burn through it pretty fast and with minimal problems. I was on off heals and the Hunters Bear pet was a handy off tank for those side pulls. Overall a good group for our needs.

Before going in for the first time see if you can pick up the couple of quests for inside. You can get these from the camp in Coldarra by the Griffin handler. There is one where you’ve got to find a book for some research and another where you’ve got to collect 5 shards. Get those quests, jump in a Nexus group and get in there!

The graphics are nice inside with a whole underground ice cave theme that goes along well with the lore for the new expansion. Upon entering you’ve got a decent area to setup and buff without worry of patrols. There will be a few wandering level 71-72 Elites at first, a ways off, that you can pull at will. Also you’ll be looking at an Elite Boss named Keristrasza frozen in a big block of ice. Leave him alone for now. There are three under bosses you’ll want to take out prior to waking this guy up.

As you progress from the entryway, through the first set of hallways that form a diamond shape, there are only a few solo wandering mob’s to worry about. Once you wander out of the hallways, however things get a bit more crowded. Like many instances this is a multi level arrangement but it’s pretty easy to get around. One reminder on pets and Trees here. You’ll find yourself jumping down from platforms and levels. Pets and Druid Trees don’t like to jump and tend to run around to the spot. This will cause problems in the Nexus and gets worse the further in you go. Mind your pets!

The biggest pull we had was around 5 or 6 mobs at once and pretty easy to handle with the group we had. The patrol patterns are not overly complicated so there won’t be too many surprises if you you’re your eyes open. We had a total of two small accidental aggros which, for three first timers, was not too bad. Keeping the Research quest in mind you’ll find a book in the hallway full of mobs encased in ice. You’ll know it when you see it. I found the book roughly halfway down that hallway.

Here’s a quick run down on our experiences with the four bosses in The Nexus…

In this run we had no problem with Ormorok the Tree Shapper. He has a nasty little AoE where he shouts “Bleed!” and ice shards shoot up from the ground all over the place however he went down fast for us. Once down he dropped some Cleated Ice Boots which sport some nice stats.

The fight with Grand Mage Telestra was a different matter. I think this was one of only two times in the whole run that I dropped out of DPS and helped the Shammy heal. I also had to rez the Shammy at one point as well. By far the hardest fight in there for us. Telestras’ got the crazy octopus thing where she grabs two or three of four of the party with magic chains and throws you back and forth around the chamber.

The third under boss, Anomolus, is sort of a pain. He’s not that hard however there are add’s to worry about and he’ll go immune periodically for several seconds. His immunity occurs when he shrinks from his full size down to a small glowing ball of white light. He did however drop the Tome of the Lore Keepers which is a nice little off-hand piece.

The boss man? Old Keristrasza himself? Pretty nasty really. You’ve got to take out a few “guard” mobs first then his big ice cube melts and he starts going nuts. I learned after the fight it’s a good idea to keep moving when around this guy. He’s got a cone style cold attack, a cold based chain root spell and several DoT’s that do some serious damage. In fact, even thought the Telestra fight was the hardest for our group, the fight with Keristrasza caused us the most overall damage. We almost lost a couple of party members during this one however, with some frantic backup healing, we got through it.

So first impression? With one death and four blue drops, some great experience and a fun group I thought it was great. Overall a lot of fun and I was glad to have two higher level’s in the group for the first run!
