implement RC5 encryption in java

Question

I've an assignment currently to implement this RC5 encryption in my java project but I have no much idea how to achieve it.

I tried to create Cipher object as below line and it throw me exception:

Cipher desCipher = Cipher.getInstance("RC5");
***java.security.NoSuchAlgorithmException: Cannot find any provider supporting RC5***

but other provider like "DES", "RC2" working fine when I create Cipher object,

fyi, I'm using jdk6.

Answer 1

http://bouncycastle.org/ I believe have a RC5 implementation use them as your provider and see if that works.
