Module raw_signature

Tools for working with raw signature algorithms.

Structs

UnknownAlgorithmError

This error is thrown when converting from a string to SigningAlg if the algorithm string is unrecognized.

Enums

RawSignatureValidationError

Describes errors that can be identified when validating a raw signature.

RawSignerError

Describes errors that can be identified when generating a raw signature.

SigningAlg

Describes the digital signature algorithms allowed by the C2PA spec.

Traits

AsyncRawSignatureValidator

An AsyncRawSignatureValidator implementation checks a signature encoded using a specific signature algorithm and a private/public key pair.

AsyncRawSigner

Implementations of the AsyncRawSigner trait generate a cryptographic signature over an arbitrary byte array.

RawSignatureValidator

A RawSignatureValidator implementation checks a signature encoded using a specific signature algorithm and a private/public key pair.

RawSigner

Implementations of the RawSigner trait generate a cryptographic signature over an arbitrary byte array.
