Scytale is a simple wrapper library to make use of encryption with Go fast and easy.

Most of the credits goes to the wonderful go.crypto library.

Installation

Use go get to install the package:

$ go get gopkg.in/matm/scytale.v1

Tools

The bin/aesenc and bin/aeszip CLI tools allow file encryption using AES-256 operating in CBC mode, password-based encryption (PBE) and a PBKDF2 password-based key derivation function.

The former can be used to encrypt/decrypt a single file:

$ go install gopkg.in/matm/scytale.v1/bin/aesenc
$ aesenc -o out.enc myfile.pdf
$ aesenc -o myfile.pdf -d out.enc

The latter encrypts a bunch of files into a standard ZIP file:

$ go install gopkg.in/matm/scytale.v1/bin/aeszip
$ aeszip -o secure.zip *.pdf

Both aeszip -l and unzip -l can be used to list the content of the archive. All files within the archive can be decrypted and extracted with

$ aeszip -x -o . secure.zip

The second file in the archive (position 1) can be decrypted and extracted with

$ aeszip -x -o . -n 1 secure.zip

See aeszip -h output for usage.
