The combined --encryption value packed two orthogonal dimensions (cipher / AE
algorithm and id hash function) into a single string, causing a combinatorial
explosion of mode names. Key location was already split out into --key-location.
Now:
- --encryption selects only the cipher / AE algorithm:
none, authenticated, aes256-ocb, chacha20-poly1305
- --id-hash selects the id hash function: sha256 (default) or blake3
- --key-location (unchanged) selects key storage: repokey (default) or keyfile
The old combined names were removed (clean break): select a BLAKE3 suite via
--encryption ... --id-hash blake3 instead of blake3-*. aes-ocb was renamed to
aes256-ocb (key NAME shown by repo-info and ARG_NAME in JSON updated to match).
"none" has no key, so it only supports the sha256 id hash.
No on-disk format, key-type byte, or crypto behavior changes: the existing key
classes form a clean cross-product of {cipher} x {id-hash}, selected via the new
ENC_NAME / IDHASH_NAME class attributes.
