使用openssl des-ede从命令行解密,零填充和原始数据

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
    Test123123%
