▸ importPKCS8<T>(pkcs8, alg, options?): Promise<T>

Imports a PEM-encoded PKCS#8 string as a runtime-specific private key representation (KeyObject or CryptoKey). See Algorithm Key Requirements to learn about key to algorithm requirements and mapping. Encrypted keys are not supported.

example Usage

const algorithm = 'ES256'
const pkcs8 = `-----BEGIN PRIVATE KEY-----
MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0wawIBAQQgiyvo0X+VQ0yIrOaN

-----END PRIVATE KEY-----`
const ecPrivateKey = await jose.importPKCS8(pkcs8, algorithm)
