Changes between 1.0.2e and 1.1.0 [xx XXX xxxx]
+ *) EGD is no longer supported by default; use enable-egd when
+ configuring.
+ [Ben Kaduk and Rich Salz]
+
+ *) The distribution now has Makefile.in files, which are used to
+ create Makefile's when Configure is run. *Configure must be run
+ before trying to build now.*
+ [Rich Salz]
+
+ *) The return value for SSL_CIPHER_description() for error conditions
+ has changed.
+ [Rich Salz]
+
+ *) Support for RFC6698/RFC7671 DANE TLSA peer authentication.
+
+ Obtaining and performing DNSSEC validation of TLSA records is
+ the application's responsibility. The application provides
+ the TLSA records of its choice to OpenSSL, and these are then
+ used to authenticate the peer.
+
+ The TLSA records need not even come from DNS. They can, for
+ example, be used to implement local end-entity certificate or
+ trust-anchor "pinning", where the "pin" data takes the form
+ of TLSA records, which can augment or replace verification
+ based on the usual WebPKI public certification authorities.
+ [Viktor Dukhovni]
+
+ *) Revert default OPENSSL_NO_DEPRECATED setting. Instead OpenSSL
+ continues to support deprecated interfaces in default builds.
+ However, applications are strongly advised to compile their
+ source files with -DOPENSSL_API_COMPAT=0x10100000L, which hides
+ the declarations of all interfaces deprecated in 0.9.8, 1.0.0
+ or the 1.1.0 releases.
+
+ In environments in which all applications have been ported to
+ not use any deprecated interfaces OpenSSL's Configure script
+ should be used with the --api=1.1.0 option to entirely remove
+ support for the deprecated features from the library and
+ unconditionally disable them in the installed headers.
+ Essentially the same effect can be achieved with the "no-deprecated"
+ argument to Configure, except that this will always restrict
+ the build to just the latest API, rather than a fixed API
+ version.
+
+ As applications are ported to future revisions of the API,
+ they should update their compile-time OPENSSL_API_COMPAT define
+ accordingly, but in most cases should be able to continue to
+ compile with later releases.
+
+ The OPENSSL_API_COMPAT versions for 1.0.0, and 0.9.8 are
+ 0x10000000L and 0x00908000L, respectively. However those
+ versions did not support the OPENSSL_API_COMPAT feature, and
+ so applications are not typically tested for explicit support
+ of just the undeprecated features of either release.
+ [Viktor Dukhovni]
+
*) Add support for setting the minimum and maximum supported protocol.
It can bet set via the SSL_set_min_proto_version() and
SSL_set_max_proto_version(), or via the SSL_CONF's MinProtocol and
MaxProtcol. It's recommended to use the new APIs to disable
protocols instead of disabling individual protocols using
- SSL_set_options() or SSL_CONF's Protocol.
+ SSL_set_options() or SSL_CONF's Protocol. This change also
+ removes support for disabling TLS 1.2 in the OpenSSL TLS
+ client at compile time by defining OPENSSL_NO_TLS1_2_CLIENT.
[Kurt Roeckx]
*) Support for ChaCha20 and Poly1305 added to libcrypto and libssl.
exchange. The LOW ciphers currently doesn't have any ciphers in it.
[Kurt Roeckx]
- *) Make EVP_MD_CTX, EVP_MD and HMAC_CTX opaque. For HMAC_CTX, the
- following constructors and destructors were added:
+ *) Made EVP_MD_CTX, EVP_MD, EVP_CIPHER_CTX, EVP_CIPHER and HMAC_CTX
+ opaque. For HMAC_CTX, the following constructors and destructors
+ were added:
HMAC_CTX *HMAC_CTX_new(void);
void HMAC_CTX_free(HMAC_CTX *ctx);
- For EVP_MD, a complete API to create, fill and destroy such
- methods has been added. See EVP_MD_meth_new(3) for
- documentation.
+ For EVP_MD and EVP_CIPHER, complete APIs to create, fill and
+ destroy such methods has been added. See EVP_MD_meth_new(3) and
+ EVP_CIPHER_meth_new(3) for documentation.
Additional changes:
- 1) HMAC_CTX_cleanup() and EVP_MD_CTX_cleanup() were removed,
- HMAC_CTX_init() and EVP_MD_CTX_init() should be called instead
- to reinitialise and already created structure. Also,
- HMAC_CTX_init() and EVP_MD_CTX_init() now return 0 for failure
- and 1 for success (they previously had the return type void).
+ 1) EVP_MD_CTX_cleanup(), EVP_CIPHER_CTX_cleanup() and
+ HMAC_CTX_cleanup() were removed. HMAC_CTX_reset() and
+ EVP_MD_CTX_reset() should be called instead to reinitialise
+ an already created structure.
2) For consistency with the majority of our object creators and
destructors, EVP_MD_CTX_(create|destroy) were renamed to
EVP_MD_CTX_(new|free). The old names are retained as macros
[Richard Levitte]
+ *) Revamped memory debug; only -DCRYPTO_MDEBUG and -DCRYPTO_MDEBUG_ABORT
+ are used; the latter aborts on memory leaks (usually checked on exit).
+ Some undocumented "set malloc, etc., hooks" functions were removed
+ and others were changed. All are now documented.

*) In DSA_generate_parameters_ex, if the provided seed is too short,
