769519 - Expose the ability to hex-encode/decode data from XPCOM

Status: NEW

(Core :: XPCOM, enhancement)

+++ This bug was initially created as a clone of Bug #753238 +++

toolkit/identity and services/crypto need the ability to encode a raw byte array of arbitrary length as a string of hex characters, e.g. { 0x12, 0x34, 0xAF } => "1234AF". nsSyncJPAKE.cpp and IdentityCryptoService.cpp both have an implementation of this already.

We should move one of those implementations to xpcom/ and change Sync and Identity to use that implementation.

Identity only needs hex-encode, not hex-decode. I can't remember if services/crypto needs hex-decode; if not, then we may not need to implement the hex-decode function at all.

Sorry for the clone-induced spam; shrinking CC list.
