Argon2id Key Verification

Verifies a password or message against a previously derived Argon2id key or hash.

Source library: cryptography

Overview

This node is the counterpart to Argon2id Key Derivation. It takes a password and the original derivation parameters and checks if they match a given key or PHC-formatted hash string. 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 or PHC-formatted string to verify against.
• length: The desired length of the derived key in bytes. Must match the original derivation.
• salt: The original BYTESLIKE salt used for derivation.
• mode:
  • string: Verifies against a raw derived key.
  • phc: Verifies against a PHC-formatted string. The salt and parameters are taken from the string itself, so the salt, iterations, parallel_lanes, and memory_cost inputs are ignored.
• iterations: The original time cost.
• parallel_lanes: The original degree of parallelism.
• memory_cost: The original memory cost in KiB.
• ad: (Optional) The original BYTESLIKE associated data.
• secret: (Optional) The original BYTESLIKE secret data.

Outputs

• verified_status: A BOOLEAN that is True if the password matches the expected key/hash, and False otherwise.
