gulp-openssl-encrypt

A encrypt/decrypt plugin for gulp 3, generating files that can be encrypt or decrypt by openssl/travis

Usage

install gulp-openssl-encrypt as a development dependency

npm install ---save-dev gulp-openssl-encrypt

Add it to your gulpfile.js

How to encrypt a file

var encrypt = require("gulp-openssl-encrypt");
gulp.task('encrypt',function(){
    gulp.src(['plaintext.txt'])
        .pipe(encrypt({
            password: 'password',
            format: 'openssl',
            decrypt: 'false',
            algorithm: 'aes-256-cbc'
        }))
        .pipe(rename('plaintext.txt.enc'))
        .pipe(gulp.dest('./'));
});

Then you can decrypt it with openssl

openssl aes-256-cbc -k 'password' -in plaintext.txt.enc -out plaintext.decrypted.txt -d

How to decrypt a file

Generate an encrypted file with openssl

openssl aes-256-cbc -k 'password' -in plaintext.txt -out plaintext.txt.enc

Then decrypt the file with gulp-openssl-encrypt

var encrypt = require("gulp-openssl-encrypt");
gulp.task('encrypt',function(){
    gulp.src(['plaintext.txt.enc'])
        .pipe(encrypt({
            password: 'password',
            format: 'openssl',
            decrypt: 'true',
            algorithm: 'aes-256-cbc'
        }))
        .pipe(rename('plaintext.txt'))
        .pipe(gulp.dest('plaintext.txt'));
});

API

gulp-openssl-encrypt(options)

options.password

Type: String

Default: P@ssw0rd

The password to encrypt/decrypt the file

options.format

Type: String

Default: 'openssl'

The output format, openssl for openssl compatible, which is salted by default. Use raw if you don't want to add salt.

options.algorithm

Type: String

Default: 'aes-256-cbc'

The algorithm use encrypt/decrypt the file. algorithm is dependent on OpenSSL, examples are 'aes192', etc. On recent releases, openssl list-cipher-algorithms will display the available cipher algorithms.

options.decrypt

Type: boolean

Default: false

Use true if you want to decrypt the file.
