For quite sometime I've been trying to decipher the ASP .ASPXAUTH cookie and decrypt it using PHP. My reasons are huge and I need to do this, there is no alternative. In PHP so far I have successfully managed to read the data from this cookie, but I cannot seem to do it while it is encrypted. Anyway, here it goes... First you need to alter your servers Web.config file (protection needs to be set to Validation): <authentication mode="None"> <forms name=".ASPXAUTH" protection="Validation" cookieless="UseCookies" timeout="10080" enableCrossAppRedirects="true"/> </authentication> Then in a PHP

Ok, I have tried to create my own encryption/decryption methods using PHP mcrypt , and when I posted them a while back some called them "trash". They were mentioning things about "Initialization Vectors" and such. Basically, how can I make these cryptography methods better: function encrypt($key, $data){ $encrypted_data = mcrypt_cbc(MCRYPT_RIJNDAEL_192, $key, $data, MCRYPT_ENCRYPT); return base64_encode($encrypted_data); } function decrypt($key, $encryptedData){ $dec = base64_decode($encryptedData); $decrypt = mcrypt_cbc(MCRYPT_RIJNDAEL_192, $key, $dec, MCRYPT_DECRYPT); return trim($decrypt);

At the moment I am working on a project that will handle some quite sensitive personal information, although it are not backaccount numbers it is still sensitive personal information and I want to do everything I can do to encrypt and store this information inside a mysql as safely as possible. So now I am intensely looking for some security measures that could deal with this sensitive information. One easy way I found to encrypt/decrypt strings and text blocks, would be using mcrypt. But when I search on mcrypt over here on stackoverflow, I noticed that many people tell that mcrypt is

I have written the same methods in two platforms which I believe should result same thing but its not happening. I have encrypted the same text with same key which result different. Can someone figure it out why is it happening ? String: this is test Key: 1234567812345678 PHP encrypted string: ybUaKwQlRNwOjJhxLWtLYQ== C# encrypted string: r2YjEFPyDDacnPmDFcGTLA== C# functions static string Encrypt(string plainText, string key) { string cipherText; var rijndael = new RijndaelManaged() { Key = Encoding.UTF8.GetBytes(key), Mode = CipherMode.ECB, BlockSize = 128, }; ICryptoTransform encryptor =

I'm using Delphi 2009 and most of the answers I've seen here are for 2010+ I am trying to sync encryption (delphi) to decryption (php) and failing. generate the encrypted string in delphi: program Project4; {$APPTYPE CONSOLE} uses SysUtils, DCPcrypt2, DCPsha1, DCPblockciphers, DCPdes, EncdDecd; var des: tdcp_des; enc,dec: ansistring; begin try des:=tdcp_des.Create(nil); des.InitStr('test', tdcp_sha1); enc:=encodestring(des.EncryptString('this is a test')); des.Free; des:=tdcp_des.Create(nil); des.InitStr('test', tdcp_sha1); dec:=des.DecryptString(decodestring(enc)); des.Free; writeln(enc);

Trying to set up Laravel and keep getting hit with this error. I installed mcrypt through brew and it is located in /usr/local/Cellar. Any thoughts? .. It's not showing up in terminal command php -m either, if that matters. I'm running Mountaion Lion with macs native web server. Deinumite You need to enable it in your php.ini file as well and probably restart Apache. In php.ini you will find ;mcrypt.so and remove the ; from it. Or, if it's not in there, just add mcrypt.so somewhere. Also the salt option has been deprecated as of PHP 7.0.0. It is now preferred to simply use the salt that is
