net/third_party/nss/README.chromium

 Name: Network Security Services (NSS)
 URL: http://www.mozilla.org/projects/security/pki/nss/
 
 This directory includes a copy of NSS's libssl from the CVS repo at:
   :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot
 
 The snapshot was updated to the CVS tag: NSS_3_12_9_RTM
 
 Patches:
 
   * Next protocol negotiation support.
     patches/nextproto.patch
     http://codereview.chromium.org/415005
 
   * Commenting out a couple of functions because they need NSS symbols
     which may not exist in the system NSS library.
     patches/versionskew.patch
 
   * Send empty renegotiation info extension instead of SCSV unless TLS is
     disabled.
     patches/renegoscsv.patch
     https://bugzilla.mozilla.org/show_bug.cgi?id=549042
 
   * Cache the peer's intermediate CA certificates in session ID, so that
     they're available when we resume a session.  Add certificates to
     ss->ssl3.peerCertChain in the right order.
     patches/cachecerts.patch
     https://bugzilla.mozilla.org/show_bug.cgi?id=606049

     patches/ocspstapling.patch
 
   * Add support for client auth with native crypto APIs on Mac and Windows
     patches/clientauth.patch

   * Don't send a client certificate when renegotiating if the peer does not
     request one. This only happened if the previous key exchange algorithm
     was non-RSA.

 The ssl/bodge directory contains files taken from the NSS repo that we required
 for building libssl outside of its usual build environment.
