Hi , We wanted to encrypt/decrypt the voice data for transmission of RTP packets on windows mobile 5/6 handsets. We went through the LIBSRTP project and found that AES encryption algorithm is been implemented there and hence we wanted to use it directly. We have developed our own logic based on 'aes_128_cbc_hmac_sha1_96_func(...)' from xfm.c but its not working correctly. We had the following doubts:- 1) Is it possible to extract ONLY the encryption/decryption logic from LIBSRTP project and use it in other projects based on PJSIP? Has anyone tried it? If yes, how to do it? 2) What is the exact place to apply the encryption/decryption logic in PJSIP code? Right now, we are using our encryption code in 'sound_port.c' We call our encrypt method in rec_cb(..) method and Decrypt method in play_cb(...) method. Are these the right places to put encryption/decryption logic of voice data? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
