No, it doesn't. MD5 is not an encryption algorithm, it's a
hashing algorithm. Hashed strings are not supposed to be
"decrypted"; this is not what hashing is for.

Since you didn't encrypt the string, you can't decrypt it, either.
The only way to "decrypt" MD5 is to use a dictionary attack; if it
fails, only brute force is left.
