Is the Session API within the approved scope of CMVP certificate #5313? #60

Description

@R2rho

libsymcrypt.so exports SymCryptSessionSenderInit, SymCryptSessoinReceiverInit, SymCryptSessionGcmEncrypt, SymCryptSessionGcmDecrypt and SymCryptSessionDestroy (VERSION_101.). The 101.2.0 changelog describes these as enabling "multithreaded IV generation within the SymCrypt FIPS boundary."

The #5313 Security Policy does not name a Session service in its services table, and registers IV Generation - External for AES-GCM. The certificate seperately claims IG C.H Scenario 3.

When a caller uses SymCryptSessionSenderInit followed by SymCryptSessionGcmEncrypt, so that the module constructs and increments the nonce internally, is that an approved-mode use of the module under #5313? Does it satisfy the Scenario 3 claim?

Trying to understand so we can use the module in approved mode correctly. Thanks!
