我只是在这里，因为我无法格式化评论，这个问题应该被关闭和删除。这将通过命令行 openssl 实用程序验证进程的工作原理。

  pvg / tmp➤more e.php 
<？php 
 $ data ='b5057bbc04b842a96144a0f617f2820e'; 
 $ data = pack（'H *'，$ data）; 

 echo $ data; 
 pvg / tmp➤php e.php>在
 pvg / tmp➤openssl des-ede -in in -out out -d -K aaaaaaaabbbbbbbccccccccdddddddd -nopad 
 pvg / tmp➤cat out 
 Test123123％
 

I am trying to recreate some openssl php code in the command-line. I have been able to get the following php code to work:

$key = 'aaaaaaaabbbbbbbbccccccccdddddddd';
$key = pack('H*',$key);

$data = 'b5057bbc04b842a96144a0f617f2820e';
$data = pack('H*',$data);

$result = openssl_decrypt($data,'des-ede', $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING);

The Command I'm Working on (Ubuntu)

openssl des-ede -in encrypted-data.txt -out decrypted-data.txt -d -K aaaaaaaabbbbbbbbccccccccdddddddd -nopad

The Key

The key that im decrypting with is the hex value: aaaaaaaabbbbbbbbccccccccdddddddd. Can this key be passed as hex?

The Encrypted Data

The encrypted data I am passing in the encrypted-data.txt file is the hex value: b5057bbc04b842a96144a0f617f2820e. The data should decrypt to Test123123. I have tried converting the encrypted data to binary and passing it through a .bin file without success. Should this data be converted to some other format before being passed?

The Parameters

I believe I am having an issue translating the php parameters OPENSSL_RAW_DATA and OPENSSL_ZERO_PADDING to my command-line call. I have discovered the option -nopad, but am unsure if it is equivalent to the options in php

I'm only including this here since I can't format a comment and this question should probably be closed and deleted. This verifies the process works identically with the command line openssl utility

pvg /tmp ➤  more e.php 
<?php
$data = 'b5057bbc04b842a96144a0f617f2820e';
$data = pack('H*',$data);

echo $data;
pvg /tmp ➤  php e.php > in
pvg /tmp ➤  openssl des-ede -in in -out out -d -K aaaaaaaabbbbbbbbccccccccdddddddd -nopad
pvg /tmp ➤  cat out
