Hi There,
I have the encryption and decryption code in PHP working fine, but I cannot decrypt or encrypt in iOS using this lib.
My encryption and decryption code in PHP are:
Decrypt
$initializationVectorSize = mcrypt_get_iv_size(MCRYPT_BLOWFISH, 'ecb');
$initializationVector = mcrypt_create_iv($initializationVectorSize, MCRYPT_RAND);
$valor = $_GET['v'];
$valor = base64_decode($valor);
$valor = mcrypt_decrypt(MCRYPT_BLOWFISH, 'mYk3yS3c', $valor, 'ecb', $initializationVector);
$valor = trim($valor, " \x00..\x1F");
print 'Valor: ' . $valor;
Encrypt
$initializationVectorSize = mcrypt_get_iv_size(MCRYPT_BLOWFISH, 'ecb');
$initializationVector = mcrypt_create_iv($initializationVectorSize, MCRYPT_RAND);
$v = mcrypt_encrypt(MCRYPT_BLOWFISH, 'mYk3yS3c', $v, 'ecb', $initializationVector);
print base64_encode($v);
one example is the following encrypted string:
cCVGRSYKtjQhyaLfn+lumQ==
In my PHP code it decrypts fines, with the result "21988882121" (without quotes).
But in my decryption code on iOS, I don't know how to properly initialize the vector following the PHP standard.
FclBlowfish *bf = [[FclBlowfish alloc] init];
bf.Key = @"mYk3yS3c";
bf.IV = @"";
[bf prepare];
NSLog(@"decrypt %@", [bf decrypt:@"d5NXWox77nXb0InI+zP98Q==" withMode:modeEBC withPadding:paddingZero]);
Any help is much appreciated!
Thanks!
(NSString *)removePad:(NSString *)plain
{
//need add code
if (![plain length])
{
return nil;
}
NSUInteger paddedlen = [plain characterAtIndex:[plain length] - 1]; //When plain = @"" shows crash
