Lyra is a lightweight and fast encryption tool that makes protecting your sensitive files easy. 

# Features

* Simple command line encryption and decryption. 

  * Encrypting is as easy as entering: `lyra encrypt file` and to decrypting is just as simple: `lyra decrypt file`

* No need to worry about complex cipher options and configurations.

  * Lyra uses a single strong time tested cipher to protect your data. Your data is encrypted with AES-256-GCM which simultaneously provides data confidentiality, authenticity and integrity (see [authenticated encryption](https://en.wikipedia.org/wiki/Authenticated_encryption)).

  * Values that need to be unique and random (ex: salt) are generated via a cryptographically secure pseudo random number generator.

* Strong GPU and ASIC resistant KDF being used to protect your passphrase.

  * Lyra uses argon2 to make dictionary attacks and brute force guessing even harder.

* Generate strong memorable passphrases via the diceware method.

# Requirements (if building from source)

* Go 1.9 and above

* [Go Dep](https://golang.github.io/dep/) for dependency management.

# Dependencies

* [gware](https://github.com/brsmsn/gware) for diceware passphrase generation.

* [golang.org/x/crypto](https://github.com/golang/crypto) for argon2 and passphrase terminal.

* [memguard](https://github.com/awnumar/memguard) for handling keys and plaintext secrurely in memory.

# Installation

#### Binaries

* Signed [binaries](#releases) available for windows, linux and macOs available [here](https://github.com/azohra/lyra/releases).

* Simply `mv` the binary to your `$PATH`

#### Installation from source

* You can alternatively install lyra using:

  * `go get -d github.com/azohra/lyra`

  * `cd $(go env GOPATH)/src/github.com/azohra/lyra && make install`

#### Installation from Brew

* Lyra can also be installed via brew:

  * `brew install azohra/tools/lyra`
