Section 2.5.1 Fingerprint attribute

[aboba]

The current editor's draft has a typo in the description of the fingerprint attribute in Section 2.5.1:

fingerprint of type sequence
attribute" defined in [RFC4572].

This should probably say:
"The fingerprint attribute is a sequence of DOMStrings, each containing a hash-function algorithm and fingerprint, in the syntax defined in [RFC4572] Section 5."

[juberti]

Should this not be a structured object with .algorithm and .value members?

[martinthomson]

Agree with Justin. I'd rather not use DOMString either. ArrayBuffer seems most appropriate for binary data. Producing strings from those is pretty straightforward.

How about this?

dictionary RTCDtlsParameters {
RTCDtlsRole role = "auto";
sequence fingerprint;
};
dictionary RTCDtlsFingerprint {
DOMString algorithm;
DOMString value;
};

Dictionary RTCDtlsFingerprint Members

algorithm of type DOMString
One of the the hash function algorithms defined in the 'Hash function Textual Names' registry, initially specified in [RFC4572] Section 8.

value of type DOMString
The value of the certificate fingerprint, expressed utilizing the syntax of 'fingerprint' in [RFC4572] Section 5.
