Imports a PEM-encoded SPKI string as a runtime-specific public key representation (KeyObject or 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'
.
