Key Identifier Length

Panel
bgColor#FAFAFA
borderStylenone

Specifies the length of the Master Key Identifier, in bytes, sent in the SRTP packet.

The Master Key Identifier (MKI) identifies the master key from which the session key(s) were derived that authenticate and/or encrypt the particular packet.

If the MKI indicator is set to one (key identifier length > 0), the length (in octets) of the MKI field and (for the sender) the actual value of the currently active MKI (the value of the MKI indicator and length) MUST be kept fixed for the lifetime of the context.

Info

To disable the MKI in the SDP, configure this value to 0.
