vetkit.csharp.crypto.weak-pbkdf2-iterations

PBKDF2 (Rfc2898DeriveBytes) is used with fewer than 100,000 iterations (the two-argument constructors default to 1,000 iterations of SHA-1). Derived keys and password hashes are cheap to brute-force.

PBKDF2 (Rfc2898DeriveBytes) is used with fewer than 100,000 iterations (the two-argument constructors default to 1,000 iterations of SHA-1). Derived keys and password hashes are cheap to brute-force.

Category: SECURITY · Engine rule severity: WARNING

How to fix it

Use Rfc2898DeriveBytes.Pbkdf2(password, salt, 600_000, HashAlgorithmName.SHA256, 32) (OWASP 2023 guidance) or Argon2id.
