method webcrypto.SubtleCrypto.generateKey

Usage in Deno

import { type webcrypto } from "node:crypto";
SubtleCrypto.generateKey(
extractable: boolean,
keyUsages: readonly KeyUsage[],
): Promise<CryptoKeyPair>

Using the method and parameters provided in algorithm, subtle.generateKey() attempts to generate new keying material. Depending the method used, the method may generate either a single <CryptoKey> or a <CryptoKeyPair>.

The <CryptoKeyPair> (public and private key) generating algorithms supported include:

  • 'RSASSA-PKCS1-v1_5'

  • 'RSA-PSS'

  • 'RSA-OAEP'

  • 'ECDSA'

  • 'Ed25519'

  • 'Ed448'

  • 'ECDH'

  • 'X25519'

  • 'X448' The <CryptoKey> (secret key) generating algorithms supported include:

  • 'HMAC'

  • 'AES-CTR'

  • 'AES-CBC'

  • 'AES-GCM'

  • 'AES-KW'
