Is there any way to decrypt the encrypted MD5 string, given the key?

MD5 is a one-way hash. It cannot be decrypted. The closest thing to decrypting an MD5 hash would be to do a lookup against a pre-generated rainbow table. Also, I'm not sure what you mean by "I have the key". There is no "key" in an MD5 hash. Perhaps you are thinking of a salt? If your data has a salt value incorporated prior to hashing, the rainbow table approach probably won't be practical anyway.

Try Google (see Using Google To Crack MD5 Passwords) or an online DB of MD5 hashes like md5(); or GDATA (the last one contains 1,133,766,035 unique entries).

MD5 is not a encryption algorithm, it is a hashing algorithm. Read up on MD5 and Crytographic Hash Functions.

To create a MD5 hash of a string in Python you do as follows:

import hashlib
m = hashlib.md5()
m.update("String to Hash")
echo m.digest()
# '\xed\xa5\x8bA-nU\xa2\xee\xbb[_s\x130\xbd'
echo m.hexdigest() # its more common to show hashes as a hex string
# 'eda58b412d6e55a2eebb5b5f731330bd'

Message-Digest algorithm 5 is a widely-used cryptographic hash function with a 128-bit hash value. Encryption has 2 way : encrypt - decript, hash has one way - there is no decryption possible. BUT with database hash IS POSSIBLE to solve this issue.
