Hi Deepak, > Please find below the memory leaks reported by rational purifier in > Crypto++ library. if any body has any idea to remove these leaks, > please suggest. A run of 'cryptest v' using valgrind (3.4.1) does not report any leaks on Linux. In Windows, using debug malloc's to track allocations does not report any leaks other than a leak due to type_id (a known MS bug). Can you post your code so we can have a look?
