Re: [Linphone-developers] Aktivate SRTP on linphone desktop ubuntu

[Peio Rigaux]

Hello.

I took a quick look at our rcfiles, and as far as I know there is no option to enable null cipher.

By the way, the null cipher is not performing any encryption!

Yes, using the parameter you provided will enable the 128-bit AES encryption method.

You can also use the 256-bit AES encryption method :

[sip]

srtp_crypto_suites=AES_CM_256_HMAC_SHA1_80,AES_CM_256_HMAC_SHA1_32
