blowfish

I have a Coldfusion page that includes a section of code that encrypts a variable like this: <cfset data64 = toBase64(key)> <cfset encryptedID = encrypt(getUser.ID, data64, "BLOWFISH", "Base64")> We're moving the site to a .NET-based CMS, and I need to convert this page to C#, but I'm running into trouble. I've successfully converted the first line to this: byte[] keyBytes = System.Text.Encoding.UTF8.GetBytes(key); string keyBase64 = System.Convert.ToBase64String(keyBytes); I've also added the blowfish.cs class found at https://defuse.ca/blowfish.htm , but I'm a little fuzzy on how to use this

In the (not too distant) past a decision has been made (by someone who longer works here) to always 'encrypt' database IDs to something else, on the fly, whenever it was needed for external communication. Now, we've moved from PHP 5.x to PHP 7.0 for our main application, and our microservices scattered across our infrastructure are running either 7.0 or 7.1. The 7.1 servers keep throwing deprecation warnings for the mcrypt stuff. No biggie, just yet. But with PHP 7.2 around the corner, we want to keep updating and upgrading. Mcrypt is blocking. To save all the currently encrypted values in 60

I have a bunch of encrypted files that I want to decrypt (duh). I found out they are encrypted with Blowfish using a 224-bit key after some research. I know what the first few bytes of the plaintext looks like (it's kind of a header). Noting that I am not NSA nor do I have ridiculous computing power, is there any chance of me brute forcing the key within a reasonable time (eg: not the life of the universe)? I read somewhere that someone published an attack on the full-blown Blowfish (no pun intended) that reduces the search to 2^(n/2) but it mysteriously disappeared. Apparently it was some

What is the difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT? Do they both use Blowfish encryption algorithm? What is cost in an algorithm? How to set up password_hash in PHP produce a 255-hash length instead of 60? Currently PASSWORD_BCRYPT is the only algorithm supported (using CRYPT_BLWFISH), therefore there is currently no difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT . The purpose of PASSWORD_DEFAULT is to allow for the inclusion of additional algorithms in the future, whereupon PASSWORD_DEFAULT will always be used to apply the strongest supported hashing algorithm. Cost

I am running my page on PHP 5.2 that does not support CRYPT_BLOWFISH but CRYPT_MD5 , and have heard that the blowfish is much more safer than md5. Since I am not the supervisor thing, I can not upgrade PHP to a version that supports it. Is there any hack for using CRYPT_BLOWFISH on PHP 5.2? and, $hash_key = crypt($something, '$2a$anySalt'); is pasting '$2a$' at the very first side correct? quite confused. P.s. If I use crypt() with CRYPT_BLOWFISH , will bcrypt work well in the crypt() function? You can use PHPASS which has fallbacks to support systems that don't support CRYPT_BLOWFISH.

Struggling to find answers to a few basic questions about using Blowfish in Cake 2.4. AppController.php public $components = array( 'Auth' => array( 'authenticate' => array( 'Form' => array( 'fields' => array( 'username' => 'email' ), 'passwordHasher' => 'Blowfish' ) ) ), 'Cookie', 'Session' ); What now? How do I log in? UsersController.php public function login() { if (!empty($this->request->data)) { if ($this->Auth->login()) { $this->redirect($this->Auth->redirectUrl()); } } } What do I need to add to this? I'm getting the following error if I try to log in: Warning (512): Invalid salt: for
