How to implement the same as given in cisco libsrtp link for an audio file instead of a text file ? #540

Any suggestions on how to encrypt and decrypt audio file instead of text file?

Who is "we"?

shrutimohankumar commented 3 years ago

I meant to say as I followed from the cisco libsrtp github link. My requirement is to encrypt an audio file. Just wanted guidance on how to do that.

paulej commented 3 years ago

SRTP isn't intended to encrypt files. It's intended to encrypt media streamed over the internet that would otherwise be sent in the clear using RTP. As you transmit packets, you call srtp_protect() before transmitting. (There is other setup work needed beforehand and the sample code is useful for understanding that.)

Can you elaborate on what exactly the setup should be? I have understood the sample code but I am having difficulty in understanding how to use it to encrypt audio.

It might help to read RFC 3550, which describes transmission of audio and video via RTP. Then read RFC 3771, which describes the encryption procedures for RTP. LibSRTP is just an implementation of RFC 3771.

Closing this as it seams to be off topic, libSRTP is for encrypting RTP packets not media directly.
