Hello all, I've been playing around with encrypted files, trying to decrypt them independently. I've used Maple to decrypt the RSA, and openssl to decrypt the AES, sha1sum to verify the hashes, but I'm having problems with the compressed files. I (perhaps naively) thought that once I'd undone the encryption, it would be possible to extract just the compressed data and use a decompression command to retrieve the original file. I know Gnupg uses zlib by default, but I used "--personal-compress-preferences zip" to use zip instead, and tried 7z to decompress. Not only did it not work, but trying to compress the original file with 7z came up with a very different file (different size as well as content). Even when I used no compression and encrypted a 1k all-zero file, the decrypted file only had 990 zero bytes. With the redundant 16 bits in the CFB mode, and the hash digests, I know I'm doing most things right. Can anyone help with these final steps? Do there exist commands (Windows or Linux) that will compress/decompress a file in the exact same manner as Gnupg, for any or all three compression algorithms?
