Shelter block
Base unit of Shelter filesystem
Objective
- Self descriptive block
- Future proof
We can change hash and cryptographic function used without making a major version. If a vulnerability is discovered, it's easy to upgrade to new functions.
Multicodec table
We use standard multicodec code when possible.
List of code convention used by this crate:
| name | code | description | status |
|---|---|---|---|
| identity | 0x00 | raw binary | stable |
| blake3 | 0x1e | hash function | stable |
| ShelterSuperBlock | 0x31 | custom | |
| ShelterBlob | 0x32 | custom | |
| ShelterFile | 0x33 | custom | |
| ShelterTree | 0x34 | custom | |
| ShelterFileVersion | 0x35 | custom | |
| XChaCha20Poly1305 | 0x37 | AEADs | custom |
| AEZ | 0x38 | AEADs | custom |
Status
Each multicodec code has a status:
- standard - these encodings should be implemented by all implementations and are widely used.
- custom - these encodings are not standard and are only used by us
