问题 Am trying to decrypt a key encrypted by Java Triple DES function using PHP mcrypt function but with no luck. Find below the java code import javax.crypto.Cipher; import javax.crypto.spec.IvParameterSpec; import javax.crypto.spec.SecretKeySpec; public class Encrypt3DES { private byte[] key; private byte[] initializationVector; public Encrypt3DES(){ } public String encryptText(String plainText, String key) throws Exception{ //---- Use specified 3DES key and IV from other source --------------

问题 I am trying to use the mycrypt php library to decrypt the following: Key: aaaaaaaabbbbbbbbccccccccdddddddd Data: b5057bbc04b842a96144a0f617f2820e Expected Result: Test123123 The data is encrypted with 3DES with the mode ECB. The code I'm currently working with decrypts the hex value to "e2119b734b5050e3" which translates to "â›sKPPã". I have tried using open ssl which is returning "False". The code is as follows: (PHP Version 5.3.3) $key = 'aaaaaaaabbbbbbbbccccccccdddddddd'; $key = pack('H*',

问题 in a case i need to decrypt texts with diffrent keys i also need to genreate valid keys in code behind. i am using this line to generate a key. var key = Encoding.UTF8.GetString(TripleDES.Create().Key); but can't use that key in this method. it says "Specified key is not a valid size for this algorithm" how can i fix this situation? public class CryptoHelper { public string Encrypt(string toEncrypt, string key) { var toEncryptArray = Encoding.UTF8.GetBytes(toEncrypt); var keyArray = Encoding

PHP Encrypt/Decrypt with TripleDes, PKCS7, and ECB

问题 I've got my encryption function working properly however I cannot figure out how to get the decrypt function to give proper output. Here is my encrypt function: function Encrypt($data, $secret) { //Generate a key from a hash $key = md5(utf8_encode($secret), true); //Take first 8 bytes of $key and append them to the end of $key. $key .= substr($key, 0, 8); //Pad for PKCS7 $blockSize = mcrypt_get_block_size('tripledes', 'ecb'); $len = strlen($data); $pad = $blockSize - ($len % $blockSize);

问题 I need to encrypt a complete java object. I am having a code which i have seen on internet which shows how to encrypt and decrypt text not the java object. So i was confused whether this is possible to encrypt complete java object. The code which i am using is below. package security; import java.security.spec.KeySpec; import javax.crypto.Cipher; import javax.crypto.SecretKey; import javax.crypto.SecretKeyFactory; import javax.crypto.spec.DESedeKeySpec; import sun.misc.BASE64Decoder; import

问题 I have to encrypt and decrypt using tripleDES to send some information to a specific server. The server use java to decrypt and I use PHP to encrypt and decrypt data. I have tried using this PHP Equivalent for Java Triple DES encryption/decryption but it does not work for my problem. My java code is the following: Note: Cadena means "string" and Llave means "key". The java code is not mine. public class TripleDes { public static String EncryptTripleDES(String Cadena, String Llave) { String
