Secrets has been replaced by https://github.com/dcoker/biscuit.
If you are a current user of Secrets, know that Biscuit provides the same functionality and more, including multi-region support. Your existing .yml files can be migrated simply by converting the values of the YAML dictionaries into a list instead of scalars.
For example, change this:
password:
key_id: ...
key_ciphertext: ...
to:
password:
- key_id: ...
key_ciphertext: ...
