createSelfSignedCertificate

Create a self-signed certificate.

Reuses input.keyPair when provided; otherwise generates a new key pair from input.algorithm. The returned certificate uses input.subject as both issuer and subject.

function createSelfSignedCertificate(
	input: CreateSelfSignedCertificateInput,
): Promise<SelfSignedCertificateResult>

Parameters

• input: CreateSelfSignedCertificateInput — Certificate subject, key, validity, and extension settings.

Returns — The certificate plus the key pair used to sign it.

Examples

const { certificate, keyPair } = await createSelfSignedCertificate({
	subject: { commonName: 'example.com' },
	algorithm: { kind: 'ecdsa', curve: 'P-256' },
});
