New Functions
in pk11pub.h:
PK11_FindRawCertsWithSubject - Finds all certificates on the given slot
with the given subject distinguished name and returns them as DER bytes. If no
such certificates can be found, returns SECSuccess and sets *results to NULL.
If a failure is encountered while fetching any of the matching certificates,
SECFailure is returned and *results will be NULL.
Notable Changes in NSS 3.45
Bug 1540403 - Implement Delegated Credentials (draft-ietf-tls-subcerts)
This adds a new experimental function: SSL_DelegateCredential
Note: In 3.45, selfserv does not yet support delegated credentials. See
Bug 1548360.
Note: In 3.45 the SSLChannelInfo is left unmodified, while an upcoming
change in 3.46 will set SSLChannelInfo.authKeyBits to that of the delegated
credential for better policy enforcement. See Bug 1563078.
Bug 1550579 - Replace ARM32 Curve25519 implementation with one from
fiat-crypto
Bug 1551129 - Support static linking on Windows
Bug 1552262 - Expose a function PK11_FindRawCertsWithSubject for finding
certificates with a given subject on a given slot
Bug 1546229 - Add IPSEC IKE support to softoken
Bug 1554616 - Add support for the Elbrus lcc compiler (<=1.23)
Bug 1543874 - Expose an external clock for SSL
This adds new experimental functions: SSL_SetTimeFunc,
SSL_CreateAntiReplayContext, SSL_SetAntiReplayContext, and
SSL_ReleaseAntiReplayContext.
The experimental function SSL_InitAntiReplay is removed.
Bug 1546477 - Various changes in response to the ongoing FIPS review
Note: The source package size has increased substantially due to the
new FIPS test vectors. This will likely prompt follow-on work, but please
accept our apologies in the meantime.
