![]() $ mdecrypt -z clear_text.gz.nc #Decrypt & Decompress Using mcrypt $ mcrypt -z clear_text #Compress & Encrypt One benefit of using gpg is that is uses standard OpenPGP formats, so any encryption software that supports OpenPGP will be able to decrypt it. Gpg will compress the input file before encryption by default, -c means to use symmetric encryption with a password. ![]() $ gpg -d clear_text.gpg #Decrypt & Decompress Using gpg $ gpg -c clear_text #Compress & Encrypt These examples compress and encrypt a file called clear_text. One thing to note is that if you're going to use separate compression and encryption tools you should always compress before encryption, since encrypted data is essentially non-compressible. For details on AES encryption method, please refer to from Wikipedia.Here's a few ways to do this.In particular, encrypted files can be deleted from a Zip file, or renamed within a Zip file while new, unencrypted files can be added to a Zip file without a password.7-Zip uses password-based encryption, and even a strong encryption algorithm like AES is of little or no benefit if the passwords you use are weak, or you do not keep track of them in a secure manner.To open the file, you will need to provide the password. ![]()
