/**
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

I tried the generated hash with PHP. password_verify returns TRUE

- 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)
- checkpw (plaintext As String, hashed As String) As Boolean
- Functions:
B4X:
Dim bc As BCrypt
Dim hash As String = bc.hashpw("Test",bc.gensalt)
Log(hash) ' $2a$10$2OA3heI7jImo7SFlFrfSK.9z6K7fF3Ny3vw3CZ3u24QvkRDSPYE6u
PHP:
$pw = "$2a$10$2OA3heI7jImo7SFlFrfSK.9z6K7fF3Ny3vw3CZ3u24QvkRDSPYE6u";
if (password_verify("Test",$pw) == true){
echo "password_verify returns TRUE";
} else {
echo "password_verify returns FALSE";
