Class SigningMetadata

Namespace

AsiBackbone.Core.Signing

Assembly

AsiBackbone.Core.dll

Represents provider-neutral signing metadata that can be carried by audit receipts, emission records, or provider adapters without requiring a concrete signing implementation.

Remarks

The metadata stores key references and signature descriptors only. It must not contain raw signing secrets, private keys, connection strings, credentials, or provider-specific secret material.

public bool HasKeyReference { get; }

Property Value

bool

HasMetadata

public bool HasMetadata { get; }

Property Value

bool

HasSignature

Gets a value indicating whether a signature value or signature reference is present.

public bool HasSignature { get; }

Property Value

bool

HashAlgorithm

Gets the hash algorithm or hash descriptor associated with SigningHash, when supplied.

public string? HashAlgorithm { get; }

Property Value

string

IsSigned

Gets a value indicating whether this metadata represents a signed artifact.

public bool IsSigned { get; }

Property Value

bool

KeyId

Gets the signing key identifier, when supplied by a host or signing provider.

string

KeyVersion

Gets the signing key version, when supplied by a host or signing provider.

public string? KeyVersion { get; }

Property Value

string

Metadata

Gets additional provider-neutral signing metadata.

public IReadOnlyDictionary<string, string> Metadata { get; }

Property Value

IReadOnlyDictionary<string, string>

NoSignature

Gets metadata with no hash, key reference, signature, provider, or signed timestamp.

public static SigningMetadata NoSignature { get; }

Property Value

SigningMetadata

Provider

Gets the provider or key-management system descriptor, when supplied.

public string? Provider { get; }

Property Value

string

Signature

Gets the provider-neutral signature value or encoded signature reference, when supplied.

public string? Signature { get; }

Property Value

string

SignatureAlgorithm

Gets the provider-neutral signature algorithm descriptor, when supplied.

public string? SignatureAlgorithm { get; }

Property Value

string

SignedUtc

Gets the UTC timestamp when the signature was produced, when supplied.

public DateTimeOffset? SignedUtc { get; }

Property Value

DateTimeOffset?

SigningHash

Gets the hash that was signed or is intended to be signed, when supplied by the host or signing provider.

public string? SigningHash { get; }

Property Value

string
