decrypt.js

// An example of decrypting AES/ECB/PKCS5Padding-encrypted buffer in node.js.
// Hope this gist will help you. Feel free to discuss with me.

var crypto = require('crypto');

// Change this to fit your needs.
// The buffer of your raw password.
var keyBuffer = new Buffer('12345678');
// The buffer of your data to be decrypted.
var encryptedBuffer = new Buffer('12345678');

// ECB mode won't need IV, so keep it like this and it will work well.
var ivBuffer = new Buffer('');

// crypto.createDecipher() receives argument as passpharse, and uses the passpharse to generate raw password and IV.
// Which really confuses me a lot.
var decipher = crypto.createDecipheriv('aes-128-ecb', keyBuffer, ivBuffer);
var chunks = [];
chunks.push(decipher.update(encryptedBuffer, 'buffer', 'hex'));
chunks.push(decipher.final('hex'));

// Use chunks.join('') to combine all parts, and then parse the hex string into Buffer object.
var decryptedBuffer = new Buffer(chunks.join(''), 'hex');
// The decryptedBuffer is what you want.
// Done.

thanks.

Thanks.
you made my day.

Thanks,

Works great, thanks!
