问题
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%
