Struct SealedBlobOpener 

pub struct SealedBlobOpener { /* private fields */ }

Opens a sealed blob’s chunks in any order. A chunk that opens is authentic — the tag covers its bytes, its position, and the header that framed it — so decryption is the whole verification and no separate hash is read.

Implementations

impl SealedBlobOpener

pub fn header(&self) -> SealedBlobHeader

pub fn open_chunk( &self, index: u64, sealed: &[u8], ) -> Result<Vec<u8>, SealedBlobError>

Open chunk index from exactly its sealed bytes. A length the header does not assign that index is refused before the cipher runs — the bytes are not that chunk, whatever they authenticate as.

pub fn open_chunks( &self, chunks: Range<u64>, sealed: &[u8], ) -> Result<Vec<u8>, SealedBlobError>

Open every chunk in chunks from the contiguous sealed bytes covering them — the span SealedBlobHeader::sealed_span names for the same range — and return their whole plaintext. Chunks are opened one at a time, so a tampered chunk fails only the reads that touch it.
