Bagaimana untuk melaksanakan penyulitan dan penyahsulitan PbeWithMd5AndDes java dalam PHP

Question

Sulitkan String statik awam(Kunci rentetan, Teks biasa String){   String encryptTxt = "";   cuba {      bait[] garam = bait baharu[8];      MessageDigest md = MessageDigest.getInstance("MD5");      md.update(key.getBytes());      byte[] digest = md.digest();      untuk (int i = 0; i < 8; i++) {         garam[i] = penghadaman[i];      }      PBEKeySpec pbeKeySpec = PBEKeySpec baharu(key.toCharArray());      SecretKeyFactory keyFactory = SecretKeyFactory            .getInstance("PBEWithMD5AndDES");      SecretKey skey = keyFactory.generateSecret(pbeKeySpec);      PBEParameterSpec paramSpec = PBEParameterSpec(garam, LElaran);      Cipher cipher = Cipher.getInstance("PBEWithMD5AndDES");      cipher.init(Cipher.ENCRYPT_MODE, skey, paramSpec);      byte[] cipherText = cipher.doFinal(plainText.getBytes());      Rentetan garamString = Rentetan baharu(Base64.encode(garam));      String ciphertextString = new String(Base64.encode(cipherText));      kembalikan saltString + ciphertextString;   } tangkapan (Pengecualian e) {      e.printStackTrace();   }   kembalikan "";}将这段java 加密使用PHP进行解密
