org.keycloak.crypto.fips.FIPSRsaKeyEncryptionJWEAlgorithmProvider

All Implemented Interfaces:

JWEAlgorithmProvider

public class FIPSRsaKeyEncryptionJWEAlgorithmProvider
extends Object
implements JWEAlgorithmProvider

Fips note: Based on https://downloads.bouncycastle.org/fips-java/BC-FJA-UserGuide-1.0.2.pdf, Section 4 There are no direct public/private key ciphers available in approved mode. Available ciphers are restricted to use for key wrapping and key transport, see section 7 and section 8 for details. Our solution is to pull out the CEK signature and encryption keys , encode them separately , and then
