BCrypt

public BCrypt()

方法详细资料

hashpw

public static String hashpw(String password,
                            String salt)
                     throws IllegalArgumentException

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

抛出:

IllegalArgumentException - if invalid salt is passed

gensalt

public static String gensalt(int log_rounds,
                             SecureRandom random)

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. Minimum 4, maximum 31.

random - an instance of SecureRandom to use

返回:

an encoded salt value

gensalt

public static String gensalt(int log_rounds)

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. Minimum 4, maximum 31.

返回:

an encoded salt value

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
