Cryptengine

Build

go build -a -o ./bin/cryptengine

Tooling Dependencies

Go

Go is the language used to build the cryptengine. You'll need to download version 1.9.2 or newer from their site here.

Glide

Glide is our vendor package manager. You can find it here. It is also recommended to install the glide plugin glide-pin, which can be installed by running the following command after installing glide: go get github.com/multiplay/glide-pin

Putting it Together

1. Clone this repo into your $GOPATH/src directory. If your $GOPATH isn't set, it's best to set it to ~/go, so that your cloned repo is in ~/go/src/cryptengine.
2. In the repo's root directory, run glide install to install the vendor dependencies.
3. You should be good to go. (See what I did there?) Try a build!

Usage

Command: cryptengine

Basic Usage

cryptengine <options> [file1 file2...]
 -e     Encrypt a file
 -d     Decrypt a file
 -gen   Generate keypair
 
 -t     Type of encryption/keys, defaults to "rsa"
 -dt    Decrypt token; currently does nothing

Generate keypair

cryptengine -gen -t rsa

Encrypt a File

cryptengine -e -t rsa file1 file2...

• Encrypts one or more files
• Supports directories
• Encrypting multiple files first creates a zip file containing the given files, then encrypts the zip file
• Skips non-standard files/directories (e.g. /dev/null, /dev/ttyS2, /dev/hda0s13, etc)
• Reports skipped files, but doesn't fail

Decrypt a File

cryptengine -d -t rsa filename

NOTE: The -t flag will be deprecated upon autoselection of correct private key based on public key hash, at which point it will be ignored

Supported Features

Encryption Methods

• RSA-4096 + AES-256
