PBKDF2HMAC Key Verification

Verifies a password against a previously derived PBKDF2HMAC key.

Source library: cryptography

Overview

This node is the counterpart to PBKDF2HMAC Key Derivation. It takes a password and the original derivation parameters and checks if they produce the expected key. This is the standard way to verify user passwords without storing them in plaintext.

Parameters

• message: The input password or message to verify, as a BYTESLIKE object.
• expected_key: The BYTESLIKE key to check against.
• length: The length of the derived key in bytes. Must match the original derivation.
• salt: The original BYTESLIKE salt used for derivation.
• iterations: The original number of iterations.
• algorithm: The original hash function used for the HMAC operation.

Outputs

• verified_status: A BOOLEAN that is True if the password hashes to the expected key, and False otherwise.
