This SDP attribute can be translated into Jingle as a <fingerprint/> element qualified by the 'urn:xmpp:tmp:jingle:apps:dtls:0' namespace, as shown below.

Additionally, the SDP setup attribute defined in &rfc4145; must be mapped, whose usage for DTLS-SRTP is defined in RFC 5763.

Note: since DTLS can be used to protect non-RTP sessions like SCTP including the fingerprint in the <encryption/> element defined in &xep0167; was deemed inappropriate. Also, the <encryption/> element defined there only applies to the encryption of the RTP data part, whereas DTLS (and DTLS-SRTP) protects the whole message.

If the Jingle initiator wishes to use DTLS-SRTP, it includes the <fingerprint/> element in its session invitation. If the initiator requires the use of DTLS, the <fingerprint/> element MUST include a 'required' attribute whose logical value is TRUE and whose lexical value is "true" or "1" &BOOLEANNOTE;, where this attribute defaults to a logical value of FALSE (i.e., a lexical value of "false" or "0").
