Welcome!
Hello! I noticed your contributions and wanted to welcome you to the Wikipedia community. I hope you like it here and decide to stay. You are welcome to edit anonymously; however, creating an account is free and has several benefits (for example, the ability to create pages, upload media and edit without one's IP address being visible to the public).

As you get started, you may find this short tutorial helpful:

Alternatively, the contributing to Wikipedia page covers the same topics.

If you have any questions, we have a friendly space where experienced editors can help you here:

If you are not sure where to help out, you can find a task here:

Please remember to sign your messages on talk pages by typing four tildes ( ~ ); this will automatically insert your username and the date.

This is your only warning; if you insert a spam link to Wikipedia again, as you did at Cryptography, you may be blocked from editing without further notice. Persistent spammers may have their websites blacklisted, preventing anyone from linking to them from all Wikimedia sites as well as potentially being penalized by search engines.
