    • hashpw

      public static String hashpw(String password, String salt)
      Hash a password using the OpenBSD bcrypt scheme
      参数:
      password - the password to hash
      salt - the salt to hash with (perhaps generated using BCrypt.gensalt)
      返回:
      the hashed password

    • hashpw

      public static String hashpw(byte[] passwordb, String salt)
      Hash a password using the OpenBSD bcrypt scheme
      参数:
      passwordb - the password to hash, as a byte array
      salt - the salt to hash with (perhaps generated using BCrypt.gensalt)
      返回:
      the hashed password

    • gensalt

      public static String gensalt(String prefix, int log_rounds, SecureRandom random) throws IllegalArgumentException
      Generate a salt for use with the BCrypt.hashpw() method
      参数:
      prefix - the prefix value (default $2a)
      log_rounds - the log2 of the number of rounds of hashing to apply - the work factor therefore increases as 2**log_rounds.
      random - an instance of SecureRandom to use
      返回:
      an encoded salt value
      抛出:
      IllegalArgumentException - if prefix or log_rounds is invalid

    • gensalt

      public static String gensalt(String prefix, int log_rounds) throws IllegalArgumentException
      Generate a salt for use with the BCrypt.hashpw() method
      参数:
      prefix - the prefix value (default $2a)
      log_rounds - the log2 of the number of rounds of hashing to apply - the work factor therefore increases as 2**log_rounds.
      返回:
      an encoded salt value
      抛出:
      IllegalArgumentException - if prefix or log_rounds is invalid

    • gensalt

      public static String gensalt(int log_rounds, SecureRandom random) throws IllegalArgumentException
      Generate a salt for use with the BCrypt.hashpw() method
      参数:
      log_rounds - the log2 of the number of rounds of hashing to apply - the work factor therefore increases as 2**log_rounds.
      random - an instance of SecureRandom to use
      返回:
      an encoded salt value
      抛出:
      IllegalArgumentException - if log_rounds is invalid

    • gensalt

      public static String gensalt(int log_rounds) throws IllegalArgumentException
      Generate a salt for use with the BCrypt.hashpw() method
      参数:
      log_rounds - the log2 of the number of rounds of hashing to apply - the work factor therefore increases as 2**log_rounds.
      返回:
      an encoded salt value
      抛出:
      IllegalArgumentException - if log_rounds is invalid

    • gensalt

      public static String gensalt(String prefix)

    • gensalt

      public static String gensalt()
      Generate a salt for use with the BCrypt.hashpw() method, selecting a reasonable default for the number of hashing rounds to apply
      返回:
      an encoded salt value

    • checkpw

      public static boolean checkpw(String plaintext, String hashed)
      Check that a plaintext password matches a previously hashed one
      参数:
      plaintext - the plaintext password to verify
      hashed - the previously-hashed password
      返回:
      true if the passwords match, false otherwise

    • checkpw

      public static boolean checkpw(byte[] passwordb, String hashed)
      Check that a password (as a byte array) matches a previously hashed one
      参数:
      passwordb - the password to verify, as a byte array
      hashed - the previously-hashed password
      返回:
      true if the passwords match, false otherwise
