md5

Is there a pure lua implementation of the md5 hashing algorithm? One that doesn't rely on any c or external libraries? There's javascript implementations that don't rely on c or anything, so it ought to be possible with lua. Thanks! Adam Baldwin I combined the mentioned lua MD5 library that required bitlib and added in LuaBit to make it a pure lua implementation. As an additional benefit it's structured in such a way that it will work inside of the redis lua scripting environment. Please note that it is extremely slow compared to other non pure lua based implementations. --[[---------------

I'm relatively new to RoR and I'm curious about why Rails compiles assets both with and without md5 hash for production? I run bundle exec rake assets:clean then bundle exec rake assets:precompile My production.rb file: MyApp::Application.configure do # Code is not reloaded between requests config.cache_classes = true # Full error reports are disabled and caching is turned on config.consider_all_requests_local = false config.action_controller.perform_caching = true # Disable Rails's static asset server (Apache or nginx will already do this) config.serve_static_assets = false # Compress

I'm currently coding my own CMS and I'm at the state of password... I want to know if I can md5 a password then sha1 it after? Like: $password = md5(sha1(mysql_real_escape_string($_POST['passw']))); You can md5 any data you'd like, even if it was hashed before. It will, however, only increase the risk of collisions because you're now working on a smaller dataset. What are you trying to achieve? Yes you can. No it doesn't make sense. The security of chained hash functions is allways equal to or less than the security of the weakest algorithm. i.e. md5(sha1($something)) is not more secure, than

I'm currently using this code for md5 hashing in Delphi 7: function MD5(const fileName : string) : string; var idmd5 : TIdHashMessageDigest5; fs : TFileStream; begin idmd5 := TIdHashMessageDigest5.Create; fs := TFileStream.Create(fileName, fmOpenRead OR fmShareDenyWrite) ; try result := idmd5.AsHex(idmd5.HashValue(fs)) ; finally fs.Free; idmd5.Free; end; end; and I'm trying to get the output the same as the PHP function md5_file() I've had a look around and common problems seem to be encoding and not padding with zeroes, but I don't know how to do either of these using TIdHashMessageDigest5 or

I am writing a application where the requirement is to transfer files from a remote SFTP server to the local machine and vice - versa. During the file transfer I want to make sure that no data packets are lost and corrupted in the transit.So the idea is to run a MD5 checksum on the remote file (residing in the sftp server) before the transfer and then start the transfer process. Once the transfer is done, run a md5 on the local file and compare the two checksums. I am using JSCH to connect to sftp server and the code is in java.But I dont know how to run a md5 on the remote file residing in

I want to re-develop my existing project to laravel. In my old system I store password into md5. Now how can I convert it according to laravel hash method for existing user. Is there any direct method to do it? Is there any direct method to do it? No there's no direct method, but you could achieve that by overriding postLogin inside Auth/AuthController.php so it will check if the password is in md5 format then recrypt it with laravel hashing method else the user will connect normally, like : public function postLogin(Request $request) { $this->validate($request, [ 'login' => 'required',
