SpletPBKDF2¶. PBKDF2 is the most widespread algorithm for deriving keys from a password, originally defined in version 2.0 of the PKCS#5 standard or in RFC2898.. It is … Splet* Constructs a PBKDF2 password encoder with a secret value as well as salt length, * iterations and hash width. * @param secret the secret * @param saltLength the salt length (in bytes) * @param iterations the number of iterations. Users should aim for taking about .5 * seconds on their own system. * @param hashWidth the size of the hash (in bits)
