Changes between 1.0.1 and 1.0.2 [xx XXX xxxx]
+ *) New option -crl_download in several openssl utilities to download CRLs
+ from CRLDP extension in certificates.
+ [Steve Henson]
+
+ *) New options -CRL and -CRLform for s_client and s_server for CRLs.
+ [Steve Henson]
+
+ *) New function X509_CRL_diff to generate a delta CRL from the difference
+ of two full CRLs. Add support to "crl" utility.
+ [Steve Henson]
+
+ *) New functions to set lookup_crls function and to retrieve
+ X509_STORE from X509_STORE_CTX.
+ [Steve Henson]
+
+ *) Print out deprecated issuer and subject unique ID fields in
+ certificates.
+ [Steve Henson]
+
+ *) Extend OCSP I/O functions so they can be used for simple general purpose
+ HTTP as well as OCSP. New wrapper function which can be used to download
+ CRLs using the OCSP API.
+ [Steve Henson]
+
+ *) Delegate command line handling in s_client/s_server to SSL_CONF APIs.
+ [Steve Henson]
+
+ *) SSL_CONF* functions. These provide a common framework for application
+ configuration using configuration files or command lines.
+ [Steve Henson]
+
+ *) SSL/TLS 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 ctrl and macro to retrieve supported points extensions.
+ Print out extension in s_server.
+ [Steve Henson]
+
+ *) New functions to retrieve certificate signature and signature
+ OID NID.
+ [Steve Henson]
+
+ *) Add functions to retrieve and manipulate the raw cipherlist sent by a
+ client to OpenSSL.
+ [Steve Henson]
+
+ *) New Suite B modes for TLS code. These use and enforce the requirements
+ of RFC6460: restrict ciphersuites, only permit Suite B algorithms and
+ only use Suite B curves. The Suite B modes can be set by using the
+ strings "SUITEB128", "SUITEB192" or "SUITEB128ONLY" for the cipherstring.
+ [Steve Henson]
+
+ *) 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]
+
+ *) Integrate hostname, email address and IP address checking with certificate
+ verification. New verify options supporting checking in opensl utility.
+ [Steve Henson]
+
+ *) Fixes and wildcard matching support to hostname and email checking
+ functions. Add manual page.
+ [Florian Weimer (Red Hat Product Security Team)]
+
+ *) New functions to check a hostname email or IP address against a
+ certificate. Add options x509 utility to print results of checks against
+ a certificate.
+ [Steve Henson]
+
+ *) Fix OCSP checking.
+ [Rob Stradling <rob.stradling@comodo.com> and Ben Laurie]
+
+ *) Backport support for partial chain verification: if an intermediate
+ certificate is explicitly trusted (using -addtrust option to x509
+ utility for example) the verification is sucessful even if the chain
+ is not complete.
+ The OCSP checking fix depends on this backport.
+ [Steve Henson and Rob Stradling <rob.stradling@comodo.com>]
+
+ *) Add -trusted_first option which attempts to find certificates in the
+ trusted store even if an untrusted chain is also supplied.
+ [Steve Henson]
+
+ *) MIPS assembly pack updates: support for MIPS32r2 and SmartMIPS ASE,
+ platform support for Linux and Android.
+ [Andy Polyakov]
+
+ *) Call OCSP Stapling callback after ciphersuite has been chosen, so
+ the right response is stapled. Also change current certificate to
+ the certificate actually sent.
+ See http://rt.openssl.org/Ticket/Display.html?id=2836.
+ [Rob Stradling <rob.stradling@comodo.com>]
+
+ *) Support for linux-x32, ILP32 environment in x86_64 framework.
+ [Andy Polyakov]
+
+ *) RFC 5878 support.
+ [Emilia Kasper, Adam Langley, Ben Laurie (Google)]
+
*) Experimental multi-implementation support for FIPS capable OpenSSL.
When in FIPS mode the approved implementations are used as normal,
when not in FIPS mode the internal unapproved versions are used instead.
Changes between 1.0.1c and 1.0.1d [xx XXX xxxx]
+ *) Make openssl verify return errors.
+ [Chris Palmer <palmer@google.com> and Ben Laurie]
+
*) Fix possible deadlock when decoding public keys.
