Main Business

Migrating LibIndy to Aries
- Indy Resolver becomes Indy-Aries-VDRI
  - Can wait to follow the DID-resolution spec, because the spec doesn't have enough detail today.
- Indy Anoncreds becomes Aries-Shared-Creds-Anoncreds or Indy-Aries-Anoncreds
  - We prefer keeping it as a separate repo in Indy until another ledger shows interest.
- Indy Wallet becomes Aries-Shared-KMS
  - Includes plugin interface
  - Aries-Shared-KMS-PostgreSQL
  - Aries-Shared-KMS-SQLite
Other themes from the Aries Connect-a-thon
Evernym can assist with:
- Consensus
- Revocation
- Rich Schemas
- DID Doc

Future Calls

January 13: Indy performance analysis (BC.gov)
Requirements question: IS-1099, should we allow duplicate credentials from the same issuer?
Non-secrets in the Indy Wallet
- Cam is working on pluggable crypto. The wallet shouldn't decide what encryption you should be using.
- Use cases where we would want to move keys between wallets
  - Moving the link secret / credential data from one device to another (synchronized storage).
  - Debug use cases
  - Richard's hit other uses cases that were better solved with DID Doc, pre-signing, signing API.
- Work-around with the web-crypto API
Migration of Indy-SDK to Aries-Core

Action items

HIPE #138, Issue #144 (Ken and Brent)
- Create a PR for changing status to ACCEPTED
- Check for an Aries RFC
PR to RFC #0019 to compare pack/upack to msgpack (Sergey)
Richard and Sergey will close old pull requests with a descriptive comment.
Mike wants to review the 61 cases of "unsafe" libindy calls and figure out if they are justified.
