```
store:
canvas:
services-jwt:
# these are all the same JWK but with different kid
# to generate a new key, run the following in a Canvas console:
#
# key = OpenSSL::PKey::RSA.generate(2048)
# key.public_key.to_jwk(kid: Time.now.utc.iso8601).to_json

- Ensure /internal/services/jwks loads correctly
- In console, ensure `CanvasSecurity::ServicesJwt.decrypt(Base64.decode64(CanvasSecurity::ServicesJwt.for_user('localhost', User.first)))`
and `CanvasSecurity::ServicesJwt.decrypt(Base64.decode64(CanvasSecurity::ServicesJwt.for_user('localhost', User.first, symmetric: true)))`
both work and produce sensible looking output
