I''m working on encrypting some data using blowfish. The previous
implementation was done using php as follows.
$key = ''some key'';
$data = ''data to be encrypted''
$iv = pack(''H*'', substr($key, 0, 16));
$literak_key =", $key.$key.$key.substr($key,16),";
$cipher = mcrypt_module_open(MCRYPT_BLOWFISH, '''',
''cbc'', '''');
mcrypt_generic_init($cipher, $literalKey, $iv);
When i try to do the same thing using rails, i get a different
encrypted key.
Also, blow fish can take only 56 byte key as its input, so i
manipulated the key as how its done in php and packed it to a hex.
however am not sure how i can pass the iv
blowfish = Crypt::Blowfish.new(key)
encrypted_string = blowfish.encrypt_block(plain_text)
any inputs?
Thanks
Ramya
