NIST SP 800-56Br2 section 6.4.2.1 requires either explicit key
confirmation (section 6.4.2.3.2), or assurance from a trusted third
party (section 6.4.2.3.1) for the KTS-OAEP key transport scheme and key
agreement schemes, but explicit key confirmation is not implemented and
cannot be implemented without protocol changes, and the FIPS provider
does not implement trusted third party validation, since it relies on
its callers to do that. We must thus mark RSA-OAEP encryption and RSASVE
as unapproved until we have received clarification from NIST on how
library modules such as OpenSSL should implement TTP validation.
This does not affect RSA-OAEP decryption, because it is approved as
a component according to the FIPS 140-3 IG, section 2.4.G.
