I was looking at the md5s in minecraft and was wondering if I could decrypt them. Does anyone know how? and no lmgtfy links.

Impossible. MD5 is a one-way encryption mechanism. It would take years to decrypt a password in MD5, plus you would have to have a huge budget. So pretty only the government has the resources and computing power to decrypt passwords. sad

What is the point of encrypting strings if they are impossible to decrypt? why save them at all.

Simple Answer: It's not encrypting--it's hashing. If I hash the password 'a', maybe I'll get the letter 'q'. But you would have to hash the whole alphabet in order to figure out which letter gets a 'q'.

Ask me if you want the complicated answer (which, basing on your question, you don't)

The point is that they can be compared against another string that has been encoded to see if they are the same.

"text" >>>> encoded

a person must then enter "text". A program can then do this:

"text" >>>>> encoded = stored encoded?

basically, only the person who knows what it was before it was encoded will know. This is a very safe way of storing passwords and personal information and validating they are correct without storing them.

Privacy
Say Company A doesn't encrypt passwords. So a hacker gets into the database and finds out everyone's passwords. Then everyone loses their personal info, and Company A goes out of business because no one will use them anymore.

Company B does encrypt passwords. When a person signs in, their input is encrypted, then checked against the database. When a hacker gets in Company B, he only finds encrypted passwords.
If they are impossible to decrypt, then the passwords are safe.
If they can be decrypted, however, then the encryption was useless.

Which reminds me...
Anyone know how MyBB encrypts passwords (just the type of enccryption)?
I want to be able to sign in to a MyBB forum remotely via an HTML form/PHP encryption, but I don't know what type the forum uses.
