Description
This checker detects the usage of
pbkdf2.Keywith fewer than 600,000 iterations. PBKDF2 is a key derivation function that applies a pseudorandom function (like HMAC-SHA256) to the password along with a salt value multiple times to produce a more secure derived key. A low number of iterations reduces the computational effort, making it easier for attackers to crack passwords. This checker is flagged as a security warning to ensure PBKDF2 is configured with a sufficiently high number of iterations.Recommendation
Use at least 600,000 iterations when calling
pbkdf2.Key.
