New in NSS 3.45
New Functionality
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.
Certificate Authority Changes
- The following CA certificates were Removed:
- Bug 1552374 - CN = Certinomis - Root CA
- SHA-256 Fingerprint: 2A99F5BC1174B73CBB1D620884E01C34E51CCB3978DA125F0E33268883BF4158

Compatibility
NSS 3.45 shared libraries are backward compatible with all older NSS 3.x shared libraries. A program linked with older NSS 3.x shared libraries will work with NSS 3.45 shared libraries without recompiling or relinking. Furthermore, applications that restrict their use of NSS APIs to the functions listed in NSS Public Functions will remain compatible with future versions of the NSS shared libraries.
Feedback
Bugs discovered should be reported by filing a bug report with bugzilla.mozilla.org (product NSS).
