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

Imports a PEM-encoded PKCS#8 string as a CryptoKey.

[!NOTE]
The OID id-RSASSA-PSS (1.2.840.113549.1.1.10) is not supported in Web Cryptography API, use the OID rsaEncryption (1.2.840.113549.1.1.1) instead for all RSA algorithms.

This function is exported (as a named export) from the main 'jose' module entry point as well as from its subpath export 'jose/key/import'.

Parameters

Parameter	Type	Description
`pkcs8`	`string`	PEM-encoded PKCS#8 string
`alg`	`string`	JSON Web Algorithm identifier to be used with the imported key. See Algorithm Key Requirements.
`options?`	`KeyImportOptions`	-

Returns

Promise<CryptoKey>
