@carsondarling/bcrypt-cli v2.0.0

Bcrypt-CLI

Provides basic tools for working with bcrypt. These are definitely not "battle-hardened", or production-worth, just something I threw together to make it a bit easier during development.

Package provides two scripts: bcrypt and debcrypt.

Both scripts have 3 different input options for the raw text: (1) via positional arguments, (2) via standard input, (3) via a password-like prompt.

In addition, bcrypt only outputs the hashed value to stdout, so that it works well with piping.

Installation

npm install -g @carsondarling/bcrypt-cli

Depending on the OS you are running on it can be necessary to install the Node.js native addon build tool and rebuild the bcrypt module:

# Install the native addon build tool
npm install -g node-gyp

# cd in the dir where node modules are (may differ depending on your distro, /usr/local/lib/node_modules is a sensible alternative)
cd /usr/lib/node_modules/
cd @carsondarling/bcrypt-cli/node_modules/bcrypt

node-gyp rebuild

Example Usage

$ bcrypt
