mcrypt

I have text encoded with Blowfish using PHP's mcrypt: $td = mcrypt_module_open ('blowfish', '', 'cfb', ''); $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td), MCRYPT_RAND); mcrypt_generic_init ($td, "somekey", $iv); $crypttext = mcrypt_generic ($td, "sometext"); mcrypt_generic_deinit ($td); $res = base64_encode($iv.$crypttext); When trying to decode the data with Node's crypto library I get garbage output. var crypto = require("crypto"), ivAndCiphertext = "base64-encoded-ciphertext", iv, cipherText, ivSize = 8, res= ""; ivAndCiphertext = new Buffer(ivAndCiphertext, 'base64'); iv = new

At first i thought it was the padding since mcrypt uses zero padding but i changed the php to use PKCS7 and get the same exact results Can anyone help? I think it has something to do with the padding in the php Test output from .Net: Key: d88f92e4fa27f6d45b49446c7fc76976 Text: Testing123 Encrypted: /DMkj7BL9Eu2LMxKhdGT+A== Encrypted after base64 decode: ?3$??K?K?,?J???

I need to exchange with a PHP API which crypts the requests and answers. On my side I am in rails 4.0.0 (ruby 2.0) and I cannot make it work. I have read a lot of answers on this subject and have tried to understand how mcrypt works, e.g. http://www.chilkatsoft.com/p/php_aes.asp , but without success. I still cannot decrypt the encrypted from PHP or encrypt something that the PHP can decrypt Could you help me please and see what I am doing wrong? PHP code: $secretKey = "1234567891234567"; $encrypt = urlencode( base64_encode( mcrypt_encrypt( MCRYPT_RIJNDAEL_128, md5($secretKey), $cleartext,

I have the following code which worked fine on PHP 5.5.9. function index() { echo $this->encryptText_3des('TEST','JHHKJH9879'); } function encryptText_3des($plainText, $key) { $key = hash("md5", $key, TRUE); for ($x=0;$x<8;$x++) { $key = $key.substr($key, $x, 1); } $padded = $this->pkcs5_pad($plainText, mcrypt_get_block_size(MCRYPT_3DES, MCRYPT_MODE_CBC)); $encrypted = base64_encode(mcrypt_encrypt(MCRYPT_3DES, $key, $padded, MCRYPT_MODE_CBC)); return $encrypted; } function pkcs5_pad ($text, $blocksize) { $pad = $blocksize - (strlen($text) % $blocksize); return $text . str_repeat(chr($pad),

Here are my requirements: I need to encrypt a string in PHP using AES encryption (including a random iv), Base64 encode it, then URL-encode it so that it can be passed as a URL parameter. I am trying to get the same result in both PHP and Ruby, but I can't make it work. Here is my PHP code: function encryptData($data,$iv){ $cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, ''); $iv_size = mcrypt_enc_get_iv_size($cipher); if (mcrypt_generic_init($cipher, 'g6zys8dlvvut6b1omxc5w15gnfad3jhb', $iv) != -1){ $cipherText = mcrypt_generic($cipher,$data ); mcrypt_generic_deinit(

Last edit: I've figured out what the problem was (see my own answer below) but I cannot mark the question as answered, it would seem. If someone can answer the questions I have in my answer below, namely, is this a bug in Cython or is this Cython's intended behavior, I will mark that answer as accepted, because that would be the most useful lesson to gain from this, IMHO. Firstly, I have to start by saying that I have been trying to figure this out for three days, and I am just banging my head against the wall. As best as I can tell from the documentation, I am doing things correctly.

I was here yesterday and got some really great answers. I took what I got and put together, what I think will be a fairly secure algorithm. I'm having a problem using blowfish with a for loop that generates the salt. I'm using base64 characters and a for loop to get a random string. I want to take this generated string and insert it into the crypt function as the salt. Because the documentation about blowfish is so sparse and the PHP docs don't really even mention it, I'm sort of stabbing in the dark here. The really strange thing is if you run this code the way it is now, it will not fail.
