|

+
|
||||
+ PK11_ImportSymKey() is a part of NSS API that becomes unavailable
|
||||
+ in the FIPS mode. Apparently NSS targets stricter restrictions
|
||||
+ than those coming from Level 1 of FIPS 140-2. In the consequence,
|
||||
+ loading a symmetric key from plain keyring or key db fails.
|
||||
+
|
||||
+ A raw crypto key is in-memory wrapped with fresh, random wrapping
|
||||
+ key just before being imported via PK11_UnwrapSymKey(). Of course,
|
||||
+ this effectively lowers to FIPS level 1. Still, this would be no
|
||||
+ different from what OpenSSL gives in the matter.
