Update from Jon and Rebecca on PKCS#11 interface spec.
Interfaces in Ursa for password hashing, AEAD, Boxes (libsodium), HMAC. indy-sdk has some implementations (Argon, chacha20poly1305, etc) of these interfaces. Some of that code could be moved in Ursa.
Jon has been asked to do a lightning talk on Ursa at the meet up on Wednesday. Would be nice to review the slides and messaging with the whole group.
