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.
Use go get to install the package:
$ go get gopkg.in/matm/scytale.v1
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.
The API doc is available on GoDoc.
