webcrypto.SubtleCrypto.sign - node__crypto.d.ts - Node

method webcrypto.SubtleCrypto.sign

Usage in Deno

```typescript import { type webcrypto } from "node:node__crypto.d.ts"; ```



SubtleCrypto.sign(algorithm: AlgorithmIdentifier
 | RsaPssParams
 | EcdsaParams
 | Ed448Params,
key: CryptoKey,
data: BufferSource,
): Promise<ArrayBuffer>

Using the method and parameters given by `algorithm` and the keying material provided by `key`, `subtle.sign()` attempts to generate a cryptographic signature of `data`. If successful, the returned promise is resolved with an `` containing the generated signature. The algorithms currently supported include: - `'RSASSA-PKCS1-v1_5'` - `'RSA-PSS'` - `'ECDSA'` - `'Ed25519'` - `'Ed448'` - `'HMAC'`

Parameters



algorithm: AlgorithmIdentifier
 | RsaPssParams
 | EcdsaParams
 | Ed448Params



key: CryptoKey



data: BufferSource

Return Type

Promise<ArrayBuffer>
