@dawaltconley/secret v0.1.0

Storing information in the Mac Keychain

Uses the OSX security cli to save and retrieve passwords and other sensitive data.

Examples

Instantiates a Secret object. Takes an argument for the service/url and an optional second argument for the account name.

const Secret = require('./secret.js')

const generic = new Secret('jekyll-comments')
// creates a generic password with no account info

const internet = new Secret('https://api.github.com', 'dawaltconley')
// creates an internet password for the account 'dawaltconley'

Following the behavior of security, Secret returns slightly different information depending on whether that Secret is of a generic or internet type.

// generic.get().then(s => console.log(s))
{
    type: 'generic',
    keychain: '/Users/dylan/Library/Keychains/login.keychain-db',
    label: 'jekyll-comments',
    account: null,
    service: 'jekyll-comments',
    password: 'passw0rd!'
}

// internet.get().then(s => console.log(s))
{
    type: 'internet',
    keychain: '/Users/dylan/Library/Keychains/login.keychain-db',
    label: 'api.github.com',
    account: 'dawaltconley',
    host: 'api.github.com',
    path: '/',
    protocol: 'https:',
    password: 'passw0rd!'
}

Configuration

Secret.prompt

Determines how the user is prompted to enter a password. Defaults to 'secret: '.

Secret.executablePath

The path of the security child process. Defaults to '/usr/bin/security'.

Methods

config()

Runs an interactive commandline prompt to assign or overwrite the secret. Adds an extra prompt to confirm overwriting, if the secret has already been set.

get(interactive)

Gets a secret from the command line. Accepts a boolean as its argument, which affects its behavior if the secret hasn't been set yet.

If set to true, get will prompt the user to input a secret (similar to config). If set to false, get will reject with a SecretNotFoundError (default: true).

set(password, force)

Sets the secret to a provided string, storing it in the Keychain. Second argument determines whether to overwrite an existing secret in the Keychain, If false, rejects with a SecretAlreadySetError (default: false).

delete()

Deletes the secret from the Keychain. Doesn't delete the secret object; secrets can still be reset or configured after deletion.
