+ *) New chain verification flags for Suite B levels of security. Check
+ algorithms are acceptable when flags are set in X509_verify_cert.
+ [Steve Henson]
+
+ *) Make tls1_check_chain return a set of flags indicating checks passed
+ by a certificate chain. Add additional tests to handle client
+ certificates: checks for matching certificate type and issuer name
+ comparison.
+ [Steve Henson]
+
+ *) If an attempt is made to use a signature algorithm not in the peer
+ preference list abort the handshake. If client has no suitable
+ signature algorithms in response to a certificate request do not
+ use the certificate.
+ [Steve Henson]
+
+ *) If server EC tmp key is not in client preference list abort handshake.
+ [Steve Henson]
+
+ *) Add support for certificate stores in CERT structure. This makes it
+ possible to have different stores per SSL structure or one store in
+ the parent SSL_CTX. Include distint stores for certificate chain
+ verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
+ to build and store a certificate chain in CERT structure: returing
+ an error if the chain cannot be built: this will allow applications
+ to test if a chain is correctly configured.
+
+ Note: if the CERT based stores are not set then the parent SSL_CTX
+ store is used to retain compatibility with existing behaviour.
+
+ [Steve Henson]
+
+ *) New function ssl_set_client_disabled to set a ciphersuite disabled
+ mask based on the current session, check mask when sending client
+ hello and checking the requested ciphersuite.
+ [Steve Henson]
+
+ *) New ctrls to retrieve and set certificate types in a certificate
+ request message. Print out received values in s_client. If certificate
+ types is not set with custom values set sensible values based on
+ supported signature algorithms.
+ [Steve Henson]
+
+ *) Support for distinct client and server supported signature algorithms.
+ [Steve Henson]
+
+ *) Add certificate callback. If set this is called whenever a certificate
+ is required by client or server. An application can decide which
+ certificate chain to present based on arbitrary criteria: for example
+ supported signature algorithms. Add very simple example to s_server.
+ This fixes many of the problems and restrictions of the existing client
+ certificate callback: for example you can now clear an existing
+ certificate and specify the whole chain.
+ [Steve Henson]
+
+ *) Add new "valid_flags" field to CERT_PKEY structure which determines what
+ the certificate can be used for (if anything). Set valid_flags field
+ in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
+ to have similar checks in it.
+
+ Add new "cert_flags" field to CERT structure and include a "strict mode".
+ This enforces some TLS certificate requirements (such as only permitting
+ certificate signature algorithms contained in the supported algorithms
+ extension) which some implementations ignore: this option should be used
+ with caution as it could cause interoperability issues.
+ [Steve Henson]
+
+ *) Update and tidy signature algorithm extension processing. Work out
+ shared signature algorithms based on preferences and peer algorithms
+ and print them out in s_client and s_server. Abort handshake if no
+ shared signature algorithms.
+ [Steve Henson]
+
+ *) Add new functions to allow customised supported signature algorithms
+ for SSL and SSL_CTX structures. Add options to s_client and s_server
+ to support them.
+ [Steve Henson]
+
+ *) New function SSL_certs_clear() to delete all references to certificates
+ from an SSL structure. Before this once a certificate had been added
+ it couldn't be removed.
+ [Steve Henson]
+
+ *) Initial SSL tracing code. This parses out SSL/TLS records using the
+ message callback and prints the results. Needs compile time option
+ "enable-ssl-trace". New options to s_client and s_server to enable
+ tracing.
+ [Steve Henson]
+
+ *) New functions to retrieve certificate signature and signature
+ OID NID.
+ [Steve Henson]
+
+ *) Print out deprecated issuer and subject unique ID fields in
+ certificates.
+ [Steve Henson]
+
+ *) RFC 5878 support.
+ [Emilia Kasper, Adam Langley, Ben Laurie (Google)]
+
+ *) Support for automatic EC temporary key parameter selection. If enabled
+ the most preferred EC parameters are automatically used instead of
+ hardcoded fixed parameters. Now a server just has to call:
+ SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically
+ support ECDH and use the most appropriate parameters.
+ [Steve Henson]
+
+ *) Enhance and tidy EC curve and point format TLS extension code. Use
+ static structures instead of allocation if default values are used.
+ New ctrls to set curves we wish to support and to retrieve shared curves.
+ Print out shared curves in s_server. New options to s_server and s_client
+ to set list of supported curves.
+ [Steve Henson]
+
+ *) New ctrls to retrieve supported signature algorithms and
+ supported curve values as an array of NIDs. Extend openssl utility
+ to print out received values.
+ [Steve Henson]
+
+ *) Add new APIs EC_curve_nist2nid and EC_curve_nid2nist which convert
+ between NIDs and the more common NIST names such as "P-256". Enhance
+ ecparam utility and ECC method to recognise the NIST names for curves.
+ [Steve Henson]
+
+ *) Enhance SSL/TLS certificate chain handling to support different
+ chains for each certificate instead of one chain in the parent SSL_CTX.
+ [Steve Henson]
+
+ *) Support for fixed DH ciphersuite client authentication: where both
+ server and client use DH certificates with common parameters.
+ [Steve Henson]
+
+ *) Support for fixed DH ciphersuites: those requiring DH server
+ certificates.
+ [Steve Henson]
+
+ *) Transparently support X9.42 DH parameters when calling
+ PEM_read_bio_DHparameters. This means existing applications can handle
+ the new parameter format automatically.
+ [Steve Henson]
+
+ *) Initial experimental support for X9.42 DH parameter format: mainly
+ to support use of 'q' parameter for RFC5114 parameters.
+ [Steve Henson]
+
+ *) Add DH parameters from RFC5114 including test data to dhtest.
+ [Steve Henson]
+
+ *) Update fips_test_suite to support multiple command line options. New
+ test to induce all self test errors in sequence and check expected
+ failures.
+ [Steve Henson]
+
+ *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
+ sign or verify all in one operation.
+ [Steve Henson]
+
+ *) Add fips_algvs: a multicall fips utility incorporaing all the algorithm
+ test programs and fips_test_suite. Includes functionality to parse
+ the minimal script output of fipsalgest.pl directly.
+ [Steve Henson]
