Module algorithm 

Which algorithm, and the parameters that go with it.

The identifier is kept as it was encoded and is not interpreted here. What may be verified with a key, and how, belongs to the algorithm registry; this layer’s job is to hand that registry exactly what the certificate said, including parameters it does not understand.

Modules

digest

Which digest an ASN.1 AlgorithmIdentifier names, resolved once for OCSP, CMS and every other ASN.1 consumer.

ml_dsa

Pure ML-DSA identities and wire sizes, without a cryptographic engine.

pss

Borrowed RSASSA-PSS parameters, without selecting a cryptographic provider.

signature

Original signature algorithm structure, without provider or policy selection.

Structs

AlgorithmIdentifier

An algorithm and its parameters, as the certificate wrote them.

AlgorithmReading

Original algorithm fields plus a recoverable parameter-syntax diagnostic.

Functions

read

Reads an algorithm identifier from an element a schema said is one.

read_implicit

Reads an original [number] IMPLICIT AlgorithmIdentifier without retagging.

read_implicit_inspection

Original IMPLICIT counterpart of read_inspection, sharing the same kernel.

read_inspection

Inspects a uniquely shaped identifier while retaining parameter syntax faults.
