B4J Library BCrypt - Create salted Hashes (compatible with PHP)

bcrypt
/**
BCrypt implements OpenBSD-style Blowfish password hashing using
the scheme described in "A Future-Adaptable Password Scheme" by
Niels Provos and David Mazieres.
This password hashing system tries to thwart off-line password
cracking using a computationally-intensive hashing algorithm,
based on Bruce Schneier's Blowfish cipher. The work factor of
the algorithm is parameterised, so it can be increased as
computers get faster.
Usage is really simple. To hash a password for the first time,
call the hashpw method with a random salt

• BCrypt
  • Functions:
    • checkpw (plaintext As String, hashed As String) As Boolean
      Check that a plaintext password matches a previously hashed
      one
      plaintext: the plaintext password to verify
      hashed: the previously-hashed password
      Return type: @return:true if the passwords match, false otherwise
    • gensalt As String
      Generate a salt for use with the BCrypt.hashpw() method,
      selecting a reasonable default for the number of hashing
      rounds to apply
      returns an encoded salt value
    • gensalt2 (log_rounds As Int) As String
      Generate a salt for use with the BCrypt.hashpw() method
      log_rounds the log2 of the number of rounds of
      hashing to apply - the work factor therefore increases as
      2**log_rounds.
      returns an encoded salt value
    • gensalt3 (log_rounds As Int, random As java.security.SecureRandom) As String
      Generate a salt for use with the BCrypt.hashpw() method
      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
      returns an encoded salt value
    • hashpw (password As String, salt As String) As String
      Hash a password using the OpenBSD bcrypt scheme
      password the password to hash
      salt the salt to hash with (perhaps generated
      using BCrypt.gensalt)
      returns the hashed password
    • Initialize (EventName As String)

    Dim bc As BCrypt
    Dim hash As String = bc.hashpw("Test",bc.gensalt)
    Log(hash) ' $2a$10$2OA3heI7jImo7SFlFrfSK.9z6K7fF3Ny3vw3CZ3u24QvkRDSPYE6u

I tried the generated hash with PHP. password_verify returns TRUE

$pw = "$2a$10$2OA3heI7jImo7SFlFrfSK.9z6K7fF3Ny3vw3CZ3u24QvkRDSPYE6u";
if (password_verify("Test",$pw) == true){
  echo "password_verify returns TRUE";
} else {
  echo "password_verify returns FALSE";
}
