go实现aes-128-ecb加密

下面是Java的demo，leader希望用golang实现，主要是我查了下资料，官方貌似是不支持aes-128-ecb加密解密的，而且限时一天，催的很紧。另外对接方提供的这个加密key是15位的，我用标准16位加密结果和Java版本跑出来结果是一致的，但是用15位golang程序就会出错，现在对这个key的填充方式表示很懵逼 (```) public static String decryptAES(String encryptResultStr, String password) { byte[] decryptFrom = parseHexStr2Byte(encryptResultStr); byte[] decryptResult = decrypt(decryptFrom, password); return new String(decryptResult); } private static byte[] decrypt(byte[] content, String password) { try { SecretKeySpec key = new SecretKeySpec(Arrays.copyOf(password.getBytes("utf-8"), 16), "AES"); Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding"); cipher.init(Cipher.DECRYPT_MODE, key); byte[] result = cipher.doFinal(content); return result; } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (NoSuchPaddingException e) { e.printStackTrace(); } catch (InvalidKeyException e) { e.printStackTrace(); } catch (IllegalBlockSizeException e) { e.printStackTrace(); } catch (BadPaddingException e) { e.printStackTrace(); } catch (IOException e){ e.printStackTrace(); } return null; } public static byte[] parseHexStr2Byte(String hexStr) { if (hexStr.length() < 1) return null; byte[] result = new byte[hexStr.length()/2]; for (int i = 0;i< hexStr.length()/2; i++) { int high = Integer.parseInt(hexStr.substring(i*2, i*2+1), 16); int low = Integer.parseInt(hexStr.substring(i*2+1, i*2+2), 16); result[i] = (byte) (high * 16 + low); } return result; } public static void main(String[] args) { String encryText = "encrypted content"; //待解密内容 System.out.print(decryptAES(encryText, "password")); //解密密钥 } (```) 以下是PHP版本的，PHP版本实现起来就比较简单 (```) function decrypt($encryptedStr, $key) { return openssl_decrypt(hex2bin($encryptedStr), 'aes-128-ecb', $key, OPENSSL_RAW_DATA); } (```)
