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.
