Module sealed_write 

Piecewise sealed write layout. Crypto supplies and authenticates the bytes.

Structs

HeaderTail

The part roots and header signature after a write’s sealed header (D9).

ObjectChunk

Coordinates, selected key and exact plaintext length of the next chunk.

WriteObjectLayout

Sealed layout cursor, retaining header metadata rather than object bytes. Writers start at the header. Readers start after opening the header with WriteObjectPrefix::opened_header. Hash each encoded piece, including the prefix and length fields, before the final signature.

WriteObjectPrefix

Cleartext key identities, authenticated by the object’s final signature.

Functions

sealed_length

The exact stored size, independent of key identities, nonces and signature contents. Header and part lengths come from the validated plaintext codec.
