Changes between 1.0.2f and 1.1.0 [xx XXX xxxx]
*) Configuration change; it's now possible to build dynamic engines
without having to build shared libraries and vice versa. The
only requirement for building dynamic engines is the presence of
the DSO module, so configuring "disable-dso" will automatically
disable dynamic engines. Dynamic engines are enabled by default,
and can be disabled with "enable-static-engine".
This only applies to the engines in engines/, those in
crypto/engine/ will always be built into libcrypto (i.e. "static").
The macros OPENSSL_NO_STATIC_ENGINE and OPENSSL_NO_DYNAMIC_ENGINE
are also taken away from openssl/opensslconf.h, as they are
irrelevant.
[Richard Levitte]
*) Configuration change; if there is a known flag to compile
position independent code, it will always be applied on the
libcrypto and libssl object files, and never on the application
object files. This means other libraries that use routines from
libcrypto / libssl can be made into shared libraries regardless
of how OpenSSL was configured.
[Richard Levitte]
*) Removed JPAKE code. It was experimental and has no wide use.
[Rich Salz]
*) The INSTALL_PREFIX Makefile variable has been renamed to
DESTDIR. That makes for less confusion on what this variable
is for. Also, the configuration option --install_prefix is
removed.
[Richard Levitte]
*) Heartbeat for TLS has been removed and is disabled by default
for DTLS; configure with enable-heartbeats. Code that uses the
old #define's might need to be updated.
[Emilia Käsper, Rich Salz]
*) Rename REF_CHECK to REF_DEBUG.
[Rich Salz]
*) New "unified" build system
The "unified" build system is aimed to be a common system for all
platforms we support. With it comes new support for VMS.
This system builds supports building in a differnt directory tree
than the source tree. It produces one Makefile (for unix family
or lookalikes), or one descrip.mms (for VMS).
The source of information to make the Makefile / descrip.mms is
small files called 'build.info', holding the necessary
information for each directory with source to compile, and a
template in Configurations, like unix-Makefile.tmpl or
descrip.mms.tmpl.
We rely heavily on the perl module Text::Template.
[Richard Levitte]
*) Added support for auto-initialisation and de-initialisation of the library.
OpenSSL no longer requires explicit init or deinit routines to be called,
except in certain circumstances. See the OPENSSL_init_crypto() and
OPENSSL_init_ssl() man pages for further information.
*) The arguments to the DTLSv1_listen function have changed. Specifically the
"peer" argument is now expected to be a BIO_ADDR object.
*) Rewrite of BIO networking library. The BIO library lacked consistent
support of IPv6, and adding it required some more extensive
modifications. This introduces the BIO_ADDR and BIO_ADDRINFO types,
which hold all types of addresses and chains of address information.
It also introduces a new API, with functions like BIO_socket,
BIO_connect, BIO_listen, BIO_lookup and a rewrite of BIO_accept.
The source/sink BIOs BIO_s_connect, BIO_s_accept and BIO_s_datagram
have been adapted accordingly.
[Richard Levitte]
*) RSA_padding_check_PKCS1_type_1 now accepts inputs with and without
the leading 0-byte.
[Emilia Käsper]
*) CRIME protection: disable compression by default, even if OpenSSL is
compiled with zlib enabled. Applications can still enable compression
by calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by
using the SSL_CONF library to configure compression.
[Emilia Käsper]
*) The signature of the session callback configured with
SSL_CTX_sess_set_get_cb was changed. The read-only input buffer
was explicitly marked as 'const unsigned char*' instead of
'unsigned char*'.
[Emilia Käsper]
*) Always DPURIFY. Remove the use of uninitialized memory in the
RNG, and other conditional uses of DPURIFY. This makes -DPURIFY a no-op.
[Emilia Käsper]
*) Removed many obsolete configuration items, including
DES_PTR, DES_RISC1, DES_RISC2, DES_INT
MD2_CHAR, MD2_INT, MD2_LONG
BF_PTR, BF_PTR2
IDEA_SHORT, IDEA_LONG
RC2_SHORT, RC2_LONG, RC4_LONG, RC4_CHUNK, RC4_INDEX
[Rich Salz, with advice from Andy Polyakov]
*) Many BN internals have been moved to an internal header file.

*) Configuration and writing out the results from it has changed.
Files such as Makefile include/openssl/opensslconf.h and are now
produced through general templates, such as Makefile.in and
crypto/opensslconf.h.in and some help from the perl module
Text::Template.
Also, the center of configuration information is no longer
Makefile. Instead, Configure produces a perl module in
configdata.pm which holds most of the config data (in the hash
table %config), the target data that comes from the target
configuration in one of the Configurations/*.conf files (in
%target).
[Richard Levitte]
*) To clarify their intended purposes, the Configure options
--prefix and --openssldir change their semantics, and become more
straightforward and less interdependent.
--prefix shall be used exclusively to give the location INSTALLTOP
where programs, scripts, libraries, include files and manuals are
going to be installed. The default is now /usr/local.
--openssldir shall be used exclusively to give the default
location OPENSSLDIR where certificates, private keys, CRLs are
managed. This is also where the default openssl.cnf gets
installed.
If the directory given with this option is a relative path, the
values of both the --prefix value and the --openssldir value will
be combined to become OPENSSLDIR.
The default for --openssldir is INSTALLTOP/ssl.
Anyone who uses --openssldir to specify where OpenSSL is to be
installed MUST change to use --prefix instead.
[Richard Levitte]
*) The GOST engine was out of date and therefore it has been removed. An up
to date GOST engine is now being maintained in an external repository.
See: https://wiki.openssl.org/index.php/Binaries. Libssl still retains
support for GOST ciphersuites (these are only activated if a GOST engine
is present).
[Matt Caswell]
*) EGD is no longer supported by default; use enable-egd when
configuring.
*) 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,
Loading full blame...
