Can't change user password, Badarg error in HTTP request (crypto,sha_mac_n)

[Nathan Vander Wilt]

I'm trying to manually set a new password for a user, but I get a 500 with a 
concerning stacktrace when I do so.

Basically what I'm doing is pulling up the _users/org.couchdb.user:doc in 
Futon, deleting the password_sha and salt fields, and adding a new field 
`password` with the desired password. When I save I get the stacktrace below.

This is CouchDB 1.3.0 on Erlang R15B02. Is this indicative of trouble with my 
build? Oddly when my app's middleware does IIRC the same thing it's fine (but 
it might be using special logic for Cloudant to hash the password locally…) 
Additionally other users *are* able to login so it can't be a completely borked 
ability to hash things as if OpenSSL lib was wrong or whatever? (Although maybe 
sha works but pbkdf2 doesn't?)

thanks,
