## [New in NSS 3.16](#new_in_nss_3.16)

### [New Functionality](#new_functionality)

:::{container}

- Supports the Linux x32 ABI. (This requires NSPR 4.10.4.) To build for the Linux x32 target,
  set the environment variable USE_X32=1 when building NSS.

```{rubric} New Functions
```

- *in cms.h*

  - **NSS_CMSSignerInfo_Verify** - verify the signature of a single SignerInfo. It just
    verifies the signature, assuming that the certificate has been verified already.

```{rubric} New Macros
```

- *in sslproto.h*

  - **TLS_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_3DES_EDE_CBC_SHA, etc.** - cipher suites that were
    first defined in SSL 3.0 can now be referred to with their official IANA names in TLS, with
    the TLS\_ prefix. Previously, they had to be referred to with their names in SSL 3.0, with
    the SSL\_ prefix.

## [Notable Changes in NSS 3.16](#notable_changes_in_nss_3.16)

:::{container}

- ECC is enabled by default. It is no longer necessary to set the environment variable
  NSS_ENABLE_ECC=1 when building NSS. To disable ECC, set the environment variable
  NSS_DISABLE_ECC=1 when building NSS.
- [Bug 903885](https://bugzilla.mozilla.org/show_bug.cgi?id=903885): (CVE-2014-1492) In a
  wildcard certificate, the wildcard character should not be embedded within the U-label of an
  internationalized domain name. See the last bullet point in [RFC 6125, Section
  7.2](https://datatracker.ietf.org/doc/html/rfc6125#section-7.2).
- [Bug 962760](https://bugzilla.mozilla.org/show_bug.cgi?id=962760): libpkix should not
  include the common name of CA as DNS names when evaluating name constraints.
- [Bug 981170](https://bugzilla.mozilla.org/show_bug.cgi?id=981170): AESKeyWrap_Decrypt
  should not return SECSuccess for invalid keys.
- [Bug 974693](https://bugzilla.mozilla.org/show_bug.cgi?id=974693): Fix a memory corruption
  in sec_pkcs12_new_asafe.
- [Bug 956082](https://bugzilla.mozilla.org/show_bug.cgi?id=956082): If the NSS_SDB_USE_CACHE
  environment variable is set, skip the runtime test sdb_measureAccess.
- The built-in roots module has been updated to version 1.97, which adds, removes, and distrusts
  several certificates.
- The atob utility has been improved to automatically ignore lines of text that aren't in base64
  format.
- The certutil utility has been improved to support creation of version 1 and version 2
  certificates, in addition to the existing version 3 support.
