Cached Credentials & LSA secrets
Please note that Cached Credentials use a different hash than LM or NTLM. The lowercase username is salted with the password.
XP Cached Credentials
The username is appended to the NTLM hash of the password and then that value is hashed using MD4 :
MD4(username + MD4(password).
Vista/Seven Cached Credentials
Uses same process to create the cached credential that XP uses, except it applies PBKDF2 as well. PBKDF2 takes the SHA1 cryptographic hash function and applies it to the XP cached credential salting it with the lower case username, repeating this for the specified number of iterations (1024).
We currently do not support cached credentials cracking. If you are interested, answer the poll !
