SHA384 and SHA512 are not yet tested since our (custom) HMAC code does not support those algorithms and rejects a block size. Note that this is only used for computing TURN MD5 and STUN SHA1 HMACs BUG=None Change-Id: Idabc651d988a5e5f3abd1fad0f36726bcc7a69a3 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/358780 Reviewed-by: Florent Castelli <orphis@webrtc.org> Commit-Queue: Philipp Hancke <phancke@meta.com> Reviewed-by: Harald Alvestrand <hta@webrtc.org> Cr-Commit-Position: refs/heads/main@{#42753}
