    • bcryptHash

      public static String bcryptHash(String password)
      Produces a Modular Crypt Format bcrypt hash of the given password, using a generated salt and 10 iterations.
      Parameters:
      password - the password to hash
      Returns:
      the Modular Crypt Format bcrypt hash of the given password
      Throws:
      NullPointerException - if the password is null

    • bcryptHash

      public static String bcryptHash(String password, int iterationCount)
      Produces a Modular Crypt Format bcrypt hash of the given password, using a generated salt and the specified iteration count.
      Parameters:
      password - the password to hash
      iterationCount - the number of iterations to use while hashing
      Returns:
      the Modular Crypt Format bcrypt hash of the given password
      Throws:
      NullPointerException - if the password is null
      IllegalArgumentException - if the iterationCount parameter is negative or zero

    • bcryptHash

      public static String bcryptHash(String password, int iterationCount, byte[] salt)
      Produces a Modular Crypt Format bcrypt hash of the given password, using the specified salt and the specified iteration count.
      Parameters:
      password - the password to hash
      iterationCount - the number of iterations to use while hashing
      salt - the salt to use while hashing
      Returns:
      the Modular Crypt Format bcrypt hash of the given password
      Throws:
      NullPointerException - if the password or salt are null
      IllegalArgumentException - if the iterationCount parameter is negative or zero, or if the salt length is not equal to 16

    • matches

      public static boolean matches(String plainText, String passwordHash)
      Matches a plain text string against an existing Modular Crypt Format bcrypt hash
      Parameters:
      plainText - the plain text string to check
      passwordHash - the Modular Crypt Format bcrypt hash to compare against
      Returns:
      the boolean result of whether the plain text matches the decoded Modular Crypt Format bcrypt hash
      Throws:
      NullPointerException - if the plainText password or passwordHash is null
