▸ generateKeyPair<T>(alg, options?): Promise<GenerateKeyPairResult<T>>

Generates a private and a public key for a given JWA algorithm identifier. This can only generate asymmetric key pairs. For symmetric secrets use the generateSecret function.

Note: Under Web Crypto API runtime the privateKey is generated with extractable set to false by default.

Type parameters

Name	Type
T	extends KeyLike = KeyLike

Parameters

Name	Type	Description
alg	string	JWA Algorithm Identifier to be used with the generated key pair.
options?	GenerateKeyPairOptions	Additional options passed down to the key pair generation.

Returns

Promise<GenerateKeyPairResult<T>>

Example

const { publicKey, privateKey } = await jose.generateKeyPair('PS256')
console.log(publicKey)
console.log(privateKey)
