Does anybody know what encrypting technique is JDeveloper/SQL Developer using to persist credentials?

Question

I\'d be more than interesting for me to understand which technique is being used here to persist sensible data since I\'m needing to implement a similar solution. Here\'s a

Answer 1

The length of the hash is 50 hex characters, which is 200 bits, so it may be the the hash of the password with a salt, prepended with the salt, like:

salt | hash(salt | password)

where | means concatenation.

Just speculation though. My guess would be a 40-bit salt and a SHA-1 hash, since SHA-1 produces 160-bit hashes.

Would be helpful to provide some input/output test data to check against!
