Symmetric File Encryption Using GPG

Provides easy symmetric file encryption using GPG with cryptographically strong defaults. Only symmetric encryption is supported. GPG is pre-installed with most Linux distributions. Windows users will need to install 'Gpg4win' ( http://www.gpg4win.org/). OS X users will need to install 'GPGTools' ( https://gpgtools.org/).

rcrypt

The rcrypt package provides easy symmetric file encryption using GPG with cryptographically strong defaults. Only symmetric encryption is supported.

Examples
