Class FingerprintAttribute

java.lang.Object

org.restcomm.media.sdp.fields.AttributeField

org.restcomm.media.sdp.dtls.attributes.FingerprintAttribute

All Implemented Interfaces:

SdpField

public class FingerprintAttribute
extends AttributeField

a=fingerprint:[hash-function][fingerprint]

Example:
a=fingerprint:sha-256 D1:2C:BE:AD:C4:F6:64:5C:25:16:11:9C:AF:E7:0F:73:79:36: 4E:9C:1E:15:54:39:0C:06:8B:ED:96:86:00:39

The fingerprint is the result of a hash function of the certificates used in the DTLS-SRTP negotiation. This line creates a binding between the signaling (which is supposed to be trusted) and the certificates used in DTLS, if the fingerprint doesn’t match, then the session should be rejected.
