Function sign

sign<H extends HashAlgorithm, A extends SignatureAlgorithm = SignatureAlgorithm>(
options: SignOptions<H, A>,
): Promise<SignResult<H, A>>
Signs a digest your page prepares for the certificate the person chooses. One confirmation window per call: the certificate is chosen there and prepare runs afterwards, because PAdES/CAdES put the certificate inside the signed attributes. prepare runs again if the person switches certificate; only the digest of the last one is signed.

The types follow your options: sign({ hash: "SHA-384", algorithm: "ECDSA", … }) gives prepare a context whose hash is "SHA-384" and algorithm is "ECDSA", and resolves with a result typed the same way.
Type Parameters
- H extends HashAlgorithm
- A extends SignatureAlgorithm = SignatureAlgorithm
Parameters
- options: SignOptions<H, A>
Returns Promise<SignResult<H, A>>
Example
```
const { signature, certificate, algorithm } = await sign({
  hash: "SHA-256",
  prepare: (certificate, { hash, algorithm }) =>
    crypto.subtle.digest(hash, signedAttributesFor(certificate, algorithm)),
});
```
Throws
InvalidRequest (bad options or digest length), Aborted (signal fired or prepare threw; the original is cause), ExtensionMissing, AppMissing, UserCancelled, PinLocked, Timeout… Each error's hint says what to do.
