A username is an account set up by a computer administrator. An administrator has full access of the data stored and can do such things as add or remove software. A username is good because it allows multiple people to use the same computer but at the same time restricting access if desired. Passwords are group of characters that are encrypted to prevent or slow down access to unwanted users. Most PC user do not have the software like ophcrack to hack and obtain passwords.
Passwords work by maintaining a list of users along with their passwords. To gain entry you must enter the username and the password that corresponds with that username. Usernames and password are typically case-sensitive, so "THIS" is not the same as "this".
However, the password list cannot be stored as a plain text list of usernames and passwords because anyone who gains entry to the system can read the file and thus determine all the passwords for all the users. Nor can we simply encrypt the list because anything that can be encrypted can also be decrypted. We solve the problem by using a hash function. A hash function is a one-way function. When we pass an argument (the password) to a hash function we generate a hash value. Even if we know which specific hash function generated that hash value, it is nigh-on impossible to determine what the original argument was without trying and testing every permutation. Knowing the length would narrow the search down somewhat, but even an 8 character password has 62^8 permutations (assuming uppercase, lowercase and digital characters only), which is more than 218 trillion permutations!

You can't decrypt them, that's why it's called one-way. The only way to get the password is to encrypt guess words with the same algorithm and checking if the result matches the encrypted password. So if your encrypted password is a9d82da, guess what it might be - maybe "frank"? - and encrypt that word, and if you get 29d8afd, you know the password is not "frank", so try another word. If one of them encrypts into a9d82da, then you know that's the password.Passwords are often guessed this way by using a dictionary - a simple list of words - and automatically encrypting them one by one and comparing the result with the encrypted password. Another approach that takes much longer is to try every possible combination of characters, such as aa, ab, ac, aaa, aab, aac, aba, abb, abc, etc. This can take weeks, months, even years, depending on the algorithm used and the speed of your computer.
Data. Information is something useful to us. An encrypted letter is simply gibberish until it's decoded. Then it's info. Hope this helps!
SSL is one of the most secure methods of transferring data across the internet. Things like credit card detail, payment details, emails, usernames, passwords and all other kinds of data can be protected by SSL, and one of the most surefire ways to protect your transmitted data is a verified SSL certificate.You can read more about SSl in the Graphics Online article added as a related link.

no they do not
Username:sm22050 Password:spoil56 this works fine so try it if you want.
no
You can't. Those programs and the people who ask for your usernames and passwords are fake! Even if they claim it's real, it's still fake! They steal your usernames and passwords and other information, and put viruses on your computer!

This is not related to Roblox. Also, please do not ask for usernames and passwords.
Passwords
There are none.
HAHAHA!!!
Via encryption.
