  8. def createHash(password: String, iterations: Int = 20000, dkLength: Int = 32, cryptoAlgo: String = "HmacSHA512", saltLength: Int = 24): String

    Creates a hashed password using PBKDF2

    Creates a hashed password using PBKDF2

    this function output a string in the modified MCF format :

    p0$params$salt$key

    • p0 : version 0 of the format
    • params: 8 digit hexadecimal representation of the number of iterations concatenated with the algo name
    • salt : Base64 encoded salt
    • key : Base64 encoded derived key

    Example :

    p0$00004e20HmacSHA256$mOCtN/Scjry0uIALe4bCCrL9eL8aWEA/$hDxtqCnBF1MS5qIOxHeDAZ23QEmqdL7796I0pVJ2yvQ

    password

    the password to hash

    iterations

    the number of encryption iterations, default to 20000

    dkLength

    derived-key length, default to 32

    cryptoAlgo

    HMAC+SHA512 is the default as HMAC+SHA1 is now considered weak

    saltLength

    length of the salt, default to 24

  20. def validatePassword(password: String, hashedPassword: String): Boolean

    Validate a password against a password hash

    Validate a password against a password hash

    password

    the password to validate

    hashedPassword

    the password hash. This should be in the same format as generated by SecureHash.createHash

    returns

    true is the password is valid
