blowfish

I'm writing an encryption to my application and website, but I don't know how to correctly encrypt the string in php. Decryption is already done by this code: function decrypt_blowfish($data,$key){ $iv=pack("H*" , substr($data,0,16)); $key=pack("H*" , $key); $x =pack("H*" , substr($data,16)); $res = mcrypt_decrypt(MCRYPT_BLOWFISH, $key, $x , MCRYPT_MODE_CBC, $iv); return $res; } I tried with simple: function encrypt_blowfish($data,$key){ $iv_size = mcrypt_get_iv_size(MCRYPT_BLOWFISH, MCRYPT_MODE_CBC); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $crypttext = mcrypt_encrypt(MCRYPT_BLOWFISH,

I need to decrypt some data in Flex that is encrypted in C# and written to a file. I settled on blowfish for simplicity's sake using the as3crypto As3 library and Bruce Schneier C# library. AS3 as3crypto link Bruce Schneier C# blowfish link I can get a short string to encrypt in C# and decrypt in Flex fine however longer strings just fail to produce results and I do not know what I am missing? C#: string reportstring = "watson?"; BlowFish b = new BlowFish("04B915BA43FEB5B6"); string cipherText = b.Encrypt_ECB(reportstring); String plainText = b.Decrypt_ECB(cipherText); AS3: var txt:String =

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

I have been reading about bcrypt (application perspective). Thinking of using it to store passwords on my site. Out of some stuff that I read it suggests either ways: e.g. 1: Bcrypt is a cross platform file encryption utility from bcrypt e.g. 2: bcrypt is an adaptive password hashing algorithm which uses the Blowfish keying schedule, not a symmetric encryption algorithm. from How To Safely Store A Password bcrypt is an adaptive cryptographic hash function for passwords designed by Niels Provos and David Mazières, based on the Blowfish cipher: from bcrypt wiki What exactly is Bcrypt? It is both

I want to store secure user passwords in a MySQL database with PHP. How can I make it better? My Class: private static $algo = '$2a'; private static $cost = '$10'; private static $pepper = 'eMI8MHpEByw/M4c9o7sN3d'; public static function generateSalt($length) { $randomBinaryString = mcrypt_create_iv($length, MCRYPT_DEV_URANDOM); $randomEncodedString = str_replace('+', '.', base64_encode($randomBinaryString)); return substr($randomEncodedString, 0, $length); } public static function generateHash($password) { if (!defined('CRYPT_BLOWFISH')) die('The CRYPT_BLOWFISH algorithm is required (PHP 5.3)

This is confusing me. When I try and use the following inputs to encrypt a string with Blowfish: key = "some key" input = "input string" I get the following results: ruby: ["79af8c8ee9220bde"] php: 79af8c8ee9220bdec2d1c9cfca7b13c6 I am going to be receiving strings from a php application so I need to get these two to sync up but I don't understand why the php string would be longer. What am I missing? php code: php > require_once 'Crypt/Blowfish.php'; php > $input = "input string"; php > $key = "some key"; php > $crypt = new Crypt_Blowfish($key); php > echo bin2hex($crypt->encrypt($input));

I'm trying to set up a form to allow a user to change their password using CakePHP 2.3. The algorithm being used is blowfish. I have the following three fields: <?php echo $this->Form->input('old_password', array('type' => 'password', 'autocomplete' => 'off')); ?> <?php echo $this->Form->input('new_password', array('type' => 'password', 'autocomplete' => 'off')); ?> <?php echo $this->Form->input('new_password_confirm', array('type' => 'password', 'autocomplete' => 'off', 'label' => 'Confirm Password')); ?> Here is the code where I'm trying to verify they entered their old password correctly:

I am using some java code that encrypts the contents of a text file using Blowfish. When I convert the encrypted file back (i.e. decrypt it) the string is missing a character from the end. Any ideas why? I am very new to Java and have been fiddling with this for hours with no luck. The file war_and_peace.txt just contains the string "This is some text". decrypted.txt contains "This is some tex" (with no t on the end). Here is the java code: public static void encrypt(String key, InputStream is, OutputStream os) throws Throwable { encryptOrDecrypt(key, Cipher.ENCRYPT_MODE, is, os); } public
