compability problem with Java and Python RSA algorithm implementation
843811Dec 18 2009 — edited Dec 19 2009I have client server application. Server is writtein in python, client in java. Client receives messages from server encrypted with RSA (http://stuvel.eu/rsa), and I'm unable to decrypt it. It seems that this is RSA algorithm compatibility problem. I'm using algorithm from java.security package, instatinating Cipher object like this: c = Cipher.getInstance("RSA"); . I noticed that this algorithm produces for input blocks of lengtrh <=117 ouput block of length 128. Server I guess uses the most triviall impelentation of RSA ( (1 byte is encrypted to 1 byte) So i want to make my java algorithm compatibile with this one which server uses. How to do that ? Do i have to instatinate Cipher object in different way ? Or use another library ?
