:: ``EncSign(X)``
Sign and Encrypt to GPG key holder
``Encrypt(K,X)``
Encrypt using symmetric-key algorithm
``Hash(X)``
SHA-2/256
EncSign(X) is sign+encrypt to a PGP key holder ``B``
Encrypt(K,X) is symmetric encryption branch list
Hash(X) is SHA-256 ``L``
list of the hash (``Hi``) and key (``Ki``) for each packfile
``R``
Repository ID
B: branch list |
L: list of the hash (Hi) and key (Ki) for each packfile | To write the repository:
R: Repository ID |
| Store each packfile ``P`` as ``P'`` = ``Encrypt(Ki, P)`` in filename ``Hi``
Store Manifest as EncSign(B || L || R) | where ``Ki`` is a new random string and ``Hi = Hash(P')``
Store each packfile P as P' = Encrypt(Ki, P) in filename Hi | Store ``EncSign(B || L || R)`` in the manifest
where Hi = Hash(P') and Ki is a random string |
| To read the repository:
To read the repository |
| Decrypt and verify manifest using GPG keyring ``-> (B, L, R)``
decrypt+verify Manifest using private key -> (B, L, R) | Warn if ``R`` does not match saved Repository ID for this remote
warn if R does not match saved Repository ID for this remote | ``for each Hi, Ki in L``:
for Hi, Ki in L: | Get file ``Hi`` from the server ``-> P'``
download file Hi from the server -> P' | Verify ``Hash(P')`` matches ``Hi``
verify Hash(P') matches Hi | Decrypt ``P'`` using ``Ki`` -> ``P`` then open ``P`` with git
decrypt P' using Ki -> P then open P with git |
| Only packs mentioned in ``L`` are downloaded.
Only packs mentioned in L are downloaded.
