Notable Changes in NSS 3.52

  • Bug 1603628 - Update NSS to support PKCS #11 v3.0.

    • Note: This change modifies the CK_GCM_PARAMS struct to include the ulIvBits field which, prior to PKCS #11 v3.0, was ambiguously defined and not included in the NSS definition. If an application is recompiled with NSS 3.52+, this field must be initialized to a value corresponding to ulIvLen. Alternatively, defining NSS_PKCS11_2_0_COMPAT will yield the old definition. See the bug for more information.

  • Bug 1623374 - Support new PKCS #11 v3.0 Message Interface for AES-GCM and ChaChaPoly.

  • Bug 1612493 - Integrate AVX2 ChaCha20, Poly1305, and ChaCha20Poly1305 from HACL*.

Compatibility

NSS 3.52 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 3.52 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).
