parseCertificateDerOrThrow

Throwing core for parseCertificateDer.

Decodes a DER-encoded X.509 certificate into a ParsedCertificate, throwing on malformed input. All built-in extensions (basicConstraints, keyUsage, subjectAltNames, etc.) are decoded automatically.
Pass ParseOptions to also decode custom extensions.

function parseCertificateDerOrThrow<TMap extends ExtensionDecoderMap>(
	der: Uint8Array,
	options?: ParseOptions<TMap>,
): ParsedCertificate<TMap>

Parameters

• der: Uint8Array — Raw DER bytes of an X.509 certificate.
• options?: ParseOptions<TMap> — Custom extension decoders to apply during parsing.
