Interface SignerInformation

The CMS signer information seam. C# uses BouncyCastle's SignerInformation; the concrete implementation is supplied by the crypto backend (wave C2b) and performs ASN.1 attribute extraction and the actual (async, WebCrypto) signature verification.

interface SignerInformation {
    verify(certificate: X509Certificate): Promise<boolean>;
    getSigningTime(): Date | null;
    getSmimeCapabilities(): EncryptionAlgorithm[];
    getDigestAlgorithm(): DigestAlgorithm;
}

Methods

verify

verify(certificate: X509Certificate): Promise<boolean>
Verify the signature against the signer's certificate.
Parameters
