}Variants§
NotFound
No -----BEGIN/END C2PA MANIFEST----- block was located.
MultipleBlocks
More than one manifest block was found. Per the specification the asset shall then be treated as if no manifests were located.
EmptyReference
The block is present but the reference between the delimiters is empty.
MalformedReference(String)
The reference is neither a resolvable URI nor a data: URI.
BareCarriageReturn
The text uses bare CR (0x0D) line endings, which are unsupported by the structured-text binding method because they make line boundaries ambiguous. Convert to LF or CRLF before embedding or validating.
ManifestDecode(DecodeError)
A data:application/c2pa;base64, reference could not be Base64-decoded.
MalformedExclusion
The exclusion ranges of a data hash assertion are malformed: negative,
out of order, overlapping, or extending past the end of the asset.
Corresponds to assertion.dataHash.malformed.
HashMismatch
The recomputed data hash did not match the value in the assertion.
Corresponds to assertion.dataHash.mismatch.
UnsupportedAlgorithm(String)
A hash algorithm identifier outside the C2PA allowed list was requested.
Corresponds to algorithm.unsupported.
