java程式碼如下

/** * 加密方法 * @param key 密钥 * @param plainText 明文 * @return 密文 */ public static String encrypt(String key, String plainText){ String encryptTxt = ""; try { byte[] salt = new byte[8]; MessageDigest md = MessageDigest.getInstance("MD5"); md.update(key.getBytes()); byte[] digest = md.digest(); for (int i = 0; i < 8; i++) { salt[i] = digest[i]; } PBEKeySpec pbeKeySpec = new PBEKeySpec(key.toCharArray()); SecretKeyFactory keyFactory = SecretKeyFactory .getInstance("PBEWithMD5AndDES"); SecretKey skey = keyFactory.generateSecret(pbeKeySpec); PBEParameterSpec paramSpec = new PBEParameterSpec(salt, ITERATIONS); Cipher cipher = Cipher.getInstance("PBEWithMD5AndDES"); cipher.init(Cipher.ENCRYPT_MODE, skey, paramSpec); byte[] cipherText = cipher.doFinal(plainText.getBytes()); String saltString = new String(Base64.encode(salt)); String ciphertextString = new String(Base64.encode(cipherText)); return saltString + ciphertextString; } catch (Exception e) { e.printStackTrace(); } return ""; }

如何對該段java程式碼加密的資料使用PHP解密
