Secure Reliable Transport (SRT) passphrase & latency parameter setting

Question

Hope you all are doing well. I am trying to set parameters like passphrase and latency in srt url . But, i need to know whether while setting passphrase parameter, is it necessary to set pbkeylen value also? If yes, then what is purpose of pbkeylen parameter in passphrase ? or what is role in that srt url of pbkeylen ? Thank you.

Answer 1

As described in the documentation , pbkeylen defines the key size used for the AES encryption. It is independent of the passphrase .

It is not necessary to set it - it will default to 16 bytes (128 bit), or whatever the other end of the connection sends in the handshake if it has been set there.
