Unsupported crypto suite AES WARNING

We are using Asterisk with sdes media_encryption.
It works fine on Asterisk 18.5.1. But some warnings displays since I installed 18.7.1.

I understand this is the problem of the below changes but I can’t find how to fix this issue(how to install unsupported crypto suite)
https://gerrit.asterisk.org/c/asterisk/+/16438

I use AmazonLinux2(aarch64) and I already installed libsrtp.
Can you tell me how to install the crypto suite or remove this warnings

Although it is classified as warning, it is nothing you have to respond to. Simply ignore those log messages. I filed an issue report to lower the severity of that: ASTERISK-29785.

Anyway, to answer your question: The related issue was ASTERISK-29625. In that issue, the causing issue is ASTERISK-26190. More details in this post … Consequently, you could re-configure Asterisk to get rid of those.

However, that does not remove the message for AES-192 either. And I do not recommend to enable AES-192 for egress (especially because your libSRTP seems not enabled with OpenSSL as crypto backend). Therefore, the easiest way is to reverse that change:

cd <in your Asterisk source tree>
wget https://gerrit.asterisk.org/changes/asterisk~16436/revisions/2/patch?zip
unzip ./c1a5759.diff.zip
patch -p1 --reverse <./c1a5759.diff
make
