The NSS team has released Network Security Services (NSS) 3.24, which is
a minor release.
Below is a short summary of the changes.
Please refer to the full release notes for additional details.
* NSS softoken has been updated with the latest NIST guidance (as of 2015)
* NSS softoken has also been updated to allow NSS to run in FIPS level-1
* SSL_ConfigServerCert function has been added for configuring SSL/TLS
server sockets with a certificate and private key. This method should be
used in preference to SSL_ConfigSecureServer,
SSL_ConfigSecureServerWithCertChain, SSL_SetStapledOCSPResponses, and
* Added PORTCheapArena for temporary arenas allocated on the stack.
* SSL_ConfigServerCert - Configures an SSL/TLS socket with a certificate,
private key and other information.
* PORT_InitCheapArena - This initializes an arena that was created on
the stack. See PORTCheapArenaPool.
* PORT_DestroyCheapArena - This destroys an arena that was created on
the stack. See PORTCheapArenaPool.
* SSLExtraServerCertData - This struct is optionally passed as an argument
to SSL_ConfigServerCert. It contains supplementary information about a
certificate, such as the intended type of the certificate, stapled OCSP
responses, or signed certificate timestamps (used for certificate
* PORTCheapArenaPool - A stack-allocated arena pool, to be used for
temporary arena allocations.
* SEC_OID_TLS_ECDHE_PSK - This OID is used to govern use of the
TLS_ECDHE_PSK_WITH_AES_128_GCM_SHA256 cipher suite, which is only
used for session resumption in TLS 1.3.
* The following functions have been deprecated (applications should use the
new SSL_ConfigServerCert function instead):
* Function NSS_FindCertKEAType is now deprecated, as it reports a misleading
value for certificates that might be used for signing rather than key
* SSLAuthType has been updated to define a larger number of authentication
* The member attribute authAlgorithm of type SSLCipherSuiteInfo has been
deprecated. Instead, applications should use the newly added attribute
* ssl_auth_rsa has been renamed to ssl_auth_rsa_decrypt.
* On Linux platforms that define FREEBL_LOWHASH, a shared library has been
* Most code related to the SSL v2 has been removed, including the ability to
actively send a SSL v2 compatible client hello.
However, the server side implementation of the SSL/TLS protocol continues to
support processing of received v2 compatible client hello messages.
* NSS supports a mechanism to log SSL/TLS key material to a logfile if the
environment variable named SSLKEYLOGFILE is set. NSS has been changed to
disable this functionality in optimized builds by default. In order to enable
the functionality in optimized builds, the symbol NSS_ALLOW_SSLKEYLOGFILE
must be defined when building NSS.
* NSS has been updated to be protected against the Cachebleed attack.
* Support for DTLS compression has been disabled.
* Support for TLS 1.3 has been improved. This includes support for DTLS 1.3.
Note that TLS 1.3 support is experimental and is not suitable for production

Checking library integrity at library load time rather than first init
time. I don't have the document.:(,

Will the deprecated functions stop working right away ? Or is there a
scheduled time at which they won't be supported anymore in the future ?
The SSL_ConfigSecureServer function is very commonly used, pretty much
in all Oracle applications.
In the past, NSS has maintained binary compatibility, except in cases
where security cannot be fixed, such as SSL2 .

There are no plans to remove these. Since they are so widely used, I
expect that we may never get rid of them. However, no new features
can or will be added to these functions. For example, if you want to
use RSA-PSS, then you will need to use the new functions.
