Decrypt an AES-128 bit encrypted file

Hi,
I have an AES-128 bit encrypted file, and I was wondering how I could decrypt it (I have the password for it) under Ubuntu 8.04 LTS.

Any help would be greatly appreciated,
Flouran

Basically, are there any packages to help me decrypt the encrypted file (in either AES-128 bit or AES-256 bit, etc)?

Well, it depends on what operations (aside from AES encoding) were applied - you can try:

aespipe -d <encyptedfile >decryptedfile

Here is an example using openssl:

Code:

openssl enc -d -aes128 -in testfile.enc -out /dev/stdout

You will be prompted for the passphrase.
You may want to use an actual file for -out.
