Instead you have to use pwdcompare 'plaintext psw', 'hashed psw' to correctly compare them. Just a note, the hashes are irreversible because it's possible that two different strings could equal the same hash. In that way it's impossible to know what it originally was. It's just incredibly unlikely to come across two strings that equal the same hash, but it makes the hash more secure by not being able to decrypt it.

More accurately, you cannot decrypt a hash because a hash contains no encrypted data. Hashing is a lossy operation, encryption is not. More importantly, you cannot reverse a hash because hashing is a lossy operation. By design, there is information missing so that the hashed value cannot be used to recreate the original, insufficient information is available. The only hope of "reversal", assuming one knows the hash algorithm and salt, would be to generate a rainbow table of sorts to look up the hash's original value s.

However it turns out I just created a new user for the application and now everything is working. You can decrypt a password from SQL Server using methods in this article.

Improve this question. So, do these applications have the password stored? WHY not get the password that is stored in those applications? Should be usually plain text for some of course depends on the app — Jakub. Add a comment. Active Oldest Votes.
