Simple NodeJS Crypto with AS3Crypto Equivalent
NODEJS COFFEESCRIPT
===================
crypto = require 'crypto'
method = 'des-ecb'
key = '12345678'
txt = "Hello World"
format = 'base64'
encrypt = ($text) ->
cipher = crypto.createCipheriv method, key, ''
crypted = cipher.update $text, 'utf8', format
crypted += cipher.final format
return crypted
decrypt = ($encrypted) ->
decipher = crypto.createDecipheriv method, key, ''
decrypted = decipher.update $encrypted, format, 'utf8'
decrypted += decipher.final 'utf8'
return decrypted
console.log 'Key = '+key
console.log "Text = "+txt
console.log "Encrypted = "+encrypt(txt)
console.log "Decrypted = "+decrypt(encrypt(txt))
AS3 AS3CRYPTO
=============
package
{
import flash.display.Sprite;
import flash.utils.ByteArray;
import com.hurlant.util.*;
import com.hurlant.crypto.*;
import com.hurlant.crypto.symmetric.*;
public class Main extends Sprite
{
private var type:String = 'des-ecb';
private var key:String = '12345678'
private var txt:String ='Hello World'
private var keyBytes:ByteArray = new ByteArray();
private var pad:IPad = new PKCS5();
private var cipher:ICipher;
public function Main()
{
keyBytes.writeUTFBytes(key);
cipher = Crypto.getCipher(type, keyBytes, pad);
pad.setBlockSize(cipher.getBlockSize());
trace("Key = "+key);
trace("Text = "+txt);
trace("Encrypted = "+encrypt(txt));
trace("Decrypted = "+decrypt(encrypt(txt)));
}
private function encrypt(txt:String):String
{
var data:ByteArray = new ByteArray();
data.writeUTFBytes(txt);
cipher.encrypt(data);
return Base64.encodeByteArray(data);
}
private function decrypt(txt:String):String
{
var data:ByteArray = Base64.decodeToByteArray(txt);
cipher.decrypt(data);
return Hex.toString(Hex.fromArray(data));
}
}
}
RESULTS
=======
Key = 12345678
Text = Hello World
Encrypted = 01Jk6AecyqldguNoHIO7dw==
Decrypted = Hello World
