Error for encrypt Data by using public key

[priyesh-shukla]

Hi,

I have started the webservice integration for Income Tax bulk ITR but i am not able to encrypt the data by using public key of income tax getting following error.

Fatal error: Uncaught Exception: Unknown key size for type "http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p"

Make sure you are using the latest versions of xmlseclibs and wse-php. If you are still getting an error you will need to paste your code as the only time you should see that is if you are trying to generate a session key using the above key type - which is incompatible.
