cloak

A Command Line OTP (One Time Password) Authenticator application written in Rust that generates time-based and counter-based OTP codes.

Motivation

• Why you shouldn’t scan two-factor authentication QR codes!
• As a means of learning the Rust programming language.
• Easier to copy the OTP code from my terminal to the login form, rather than from my phone to my laptop.

Example

Installation

To install cloak, you can do either of the following:

1. Binaries

   You can download the binaries here. Make sure to put the path to the binary into your PATH.

2. Crates.io

   Once you've installed Rust, install cloak by typing the following in the terminal:

   bash cargo install cloak

   This will download and compile cloak. After this is finished, add the Cargo bin directory to your PATH.

The sub-commands included in cloak are as follows:

```bash $ cloak -h cloak 0.1.0 Evans Murithi murithievans80@gmail.com A Command Line OTP Authenticator application.

USAGE: cloak [SUBCOMMAND]

FLAGS: -h, --help Prints help information -V, --version Prints version information

SUBCOMMANDS: add Add a new account delete Delete an account help Prints this message or the help of the given subcommand(s) list List OTP for all accounts recovery_codes View recovery codes for an account view View the OTP for an account ```

To view the help of any of the subcommands below, add -h or --help, e.g. cloak add -h.

• cloak add <account> <key>

  This will add a new account. You will need to provide the name of the account as well as valid base32 encoded key. Example:

  bash $ cloak add github 4AZJFQFIGYM2KMTOO72I6FAOZ6ZFWJR6

• cloak view <account>

  This will print the TOTP/HOTP of the account you want to view. Example:

  bash $ cloak view github 123456

• cloak list

  This prints all the accounts with their respective TOTP/HOTP codes. Example:

  ```bash $ cloak list Account: github TOTP: 607091

  Account: gitlab TOTP: 325414 ```

• cloak delete <account>

  This will delete an account. Once deleted, you cannot view the OTP codes for the account. Example:

  bash $ cloak delete github Account successfully deleted $ cloak view github Account with the name 'github' does not exist. Consider adding it.

• cloak recovery_codes <account>

  This will open a file, using your preferred editor, to either save new recovery codes or view existing recovery codes.
