Maybe it's not encrypted with md5, take a look at 'man 3 crypt'

MD5 is a hash function. There is no "decrypting" it. (There are documented attacks against it, but that is a different story.)

For that matter, shell account passwords on most *nix systems I've worked with are stored as a salt + a hashed value. You can brute force it, or you can change it. But you can't decrypt it.

This is a suspicious post. Why would you want to decrypt a user password? If you are the sysadmin, change it, if you are a use as well, ask the sysadmin to change it.

ditto that: Ask the administrator to change the password. No one here should be giving answers on how to get into a system if you have lost your password.

Who owns the computer, and who is the administrator?
