nacrypt

A simple and easy to use file encryption program made using libsodium

Usage

nacrypt <input_file> -o <output_file> [-e|-d]

Example

## Encrypt
nacrypt plaintext.txt -o plaintext.txt.encrypted -e

## Decrypt
nacrypt plaintext.txt.encryted -o plaintext_decrypted.txt -d

Building

Install libsodium and libseccomp
Debian / Ubuntu: sudo apt install -y libsodium-dev libseccomp-dev

To build, simply run the makefile with:

make

seccomp

Nacrypt applies a very strict seccomp filter to itself before processing the input file. (see nacrypt_security.h)
If this causes issues it can be disabled with the -DNO_SECCOMP CFLAG or allowed to fail with -DALLOW_SECCOMP_FAIL (on platforms without seccomp)

Installation

make && sudo make install
