Encrypter

NodeJS encryption made easy.

##Installation

The source is available for download from GitHub. Alternatively, you can install using Node Package Manager (npm):

npm install encrypter

##Usage

###initialize

var encrypter = new (require('encrypter'))(encryptionKey[, cipherAlgorithm[, messageDigestAlgorithm]])

where

encryptionKey - secret string key used for encryption

cipherAlgorithm - cipher Algorithm (default: aes-256-ctr).

Cipher algorithm is dependent on the available algorithms supported by the version of OpenSSL on the node platform. examples are 'aes192', etc. On recent releases, openssl list-cipher-algorithms will display the available cipher algorithms.

messageDigestAlgorithm - message digest algorithm(default: sha1).

Message digest algorithm is dependent on the available algorithms supported by the version of OpenSSL on the node platform. Examples are 'sha1', 'md5', 'sha256', 'sha512', etc. On recent releases, openssl list-message-digest-algorithms will display the available digest algorithms.

###encrypt and decrypt

With default algorithms:

var encrypter = new (require('encrypter'))("myEncryptionSecret");

var encrypted = encrypter.encrypt('Hello from quorra!');

var decrypted = encrypter.decrypt(encrypted); // Hello from quorra!

With custom algorithms:

var encrypter = new (require('encrypter'))("myEncryptionSecret", 'aes-256-ctc', 'sha256');

var encrypted = encrypter.encrypt('Hello from quorra!');

var decrypted = encrypter.decrypt(encrypted); // Hello from quorra!
