Java code: {code ...} background: The target platform language is Java, and the parameters must be encrypted. The returned data is also encrypted and then returned. My language is a php problem: can this Javaaes class be implemented using php? If

Recently in the project, the issue of DES Encryption and decryption was encountered.Scene is the Android app side with Des encryption, PHP this side need to decrypt. No prior contact with Des this encryption and decryption algorithm, but think there

Data encryption transfer between Android and PHP [code] [Java] Code1 MCrypt =NewMCrypt ();2/*Encrypt*/3 String encrypted = Mcrypt.bytestohex (Mcrypt.encrypt ("Text to Encrypt") );4/*Decrypt*/5 String decrypted =NewString (Mcrypt.decrypt (encrypted));

PHP and Java Universal AES encryption and decryption algorithm AES refers to the Advanced Encryption Standard (encryption), is the most popular one of the current cryptographic algorithm, in Web application development, especially the external

When doing docking, the service provider AES encryption through the SHA1PRNG algorithm (as long as the password, each generation of the array is the same, so can be used to do encryption and decryption key) for another time encryption, engaged for

Class Cryptaes{protected $cipher = mcrypt_rijndael_128;protected $mode = MCRYPT_MODE_ECB;protected $pad _method = NULL;protected $secret _key = ";protected $iv = "; Public Function Set_cipher ($cipher) {$this->cipher = $cipher;} Public Function

Back up the old post and pull it ,:)---------------------------------------------------------------------------Hey, I simply wrote hex/bin both positive and negative conversions. Maybe I can copy my own program later. HIA //:
