In my application i am encrypting message using javax.crypto. and sending it through request. it is working fine but problem is whenever thereis an occurence of any one of these symbols '+' '#' '%' in the encrypted message
request.getParameter skipps that symbol and making problem on decryption.
please suggest any method to avoid these symbols.I tried with utf8 and ascii encoding with base64 encoder both give '+' symbols on encryption.

You should be URL-encoding all parameters, encrypted or not.

URLEncoder.encode("Your Encrypted String", "UTF-8");

and that's it.
