Thanks, Sam. This seems like a reasonable approach.

Hi all,
There was a brief discussion on jdev@ today about how Bits of Binary is
not consistent with newer XEPs in terms of the hash algorithm names it
uses. Currently it only mentions using the name "sha1" to refer to the
SHA-1 hash algorithm. However, other XEPs that follow the guidelines
from "XEP-0300: Use of Cryptographic Hash Functions in XMPP"
[1] say to use the names from the "IANA Hash Function Textual Names
Registry" [2] which uses the name "sha-1".
Since BoB does not actually mention what other algorithms are supported
or what they should be called, I have submitted the following text to
clarify that names should be taken from the IANA registry and XEP-0300
except if the algorithm is SHA-1 which must remain "sha1" for historical
reasons. I believe this is simpler than creating a new namespace or
entirely new mechanism for sending binary data around and is backwards
compatible with all existing implementations, but if you have arguments
to the contrary I'd love to hear them. The PR is here if you'd like to
peruse the text or suggest changes:
