I would like to use a Blowfish Decrypt Algorithm ( mode ECB) for a plugin development, how can I add it on my groovy script?

Im not sure if its a part of core Java. If yes it should not be a problem. Check the plugin guide, there is a link to Javadoc. Otherwise look at 4od plugin which includes algorithm similar to Blowfish.

Found !!
File decrypted !

import java.security.Key
import javax.crypto.spec.SecretKeySpec
import javax.crypto.Cipher

Thanks

Cant you use one of the shared methods in the plugin sdk? It uses these classes as well.

Are you talking about these shared methods?

String decryptAES(String hexText, String key, String iv)
String generateMAC(String text, String hash, String algorithm)

I don't know how to use them.

EDIT: I use this method:

import java.security.Key
import javax.crypto.spec.SecretKeySpec
import javax.crypto.Cipher

Code:: public String MyDecrypt(byte[] data,byte[] key){ try { Key clef = new SecretKeySpec(key,"DES"); Cipher c = Cipher.getInstance("DES"); c.init(Cipher.DECRYPT_MODE,clef); return new String(c.doFinal(data)); } catch (Exception e) { System.out.println(e); return null; } }

"DES" algorithm could be added to the method parameters.

ok, that is a bit different, i'll add this to a future version.
