Changes between 1.0.2g and 1.1.0 [xx XXX xxxx]
*) Remove openssl.spec. Packaging files belong with the packagers.
[Richard Levitte]
*) Automatic Darwin/OSX configuration has had a refresh, it will now
recognise x86_64 architectures automatically. You can still decide
to build for a different bitness with the environment variable
KERNEL_BITS (can be 32 or 64), for example:
KERNEL_BITS=32 ./config
[Richard Levitte]
*) Change default algorithms in pkcs8 utility to use PKCS#5 v2.0,
256 bit AES and HMAC with SHA256.
[Steve Henson]
*) Remove support for MIPS o32 ABI on IRIX (and IRIX only).
[Andy Polyakov]
*) Triple-DES ciphers have been moved from HIGH to MEDIUM.
*) To enable users to have their own config files and build file templates,
Configure looks in the directory indicated by the environment variable
OPENSSL_LOCAL_CONFIG_DIR as well as the in-source Configurations/
directory. On VMS, OPENSSL_LOCAL_CONFIG_DIR is expected to be a logical
name and is used as is.
[Richard Levitte]
*) The following datatypes were made opaque: X509_OBJECT, X509_STORE_CTX,
X509_STORE, X509_LOOKUP, and X509_LOOKUP_METHOD. The unused type
X509_CERT_FILE_CTX was removed.
[Rich Salz]
*) "shared" builds are now the default. To create only static libraries use
the "no-shared" Configure option.
[Matt Caswell]
*) Remove the no-aes, no-hmac, no-rsa, no-sha and no-md5 Configure options.
All of these option have not worked for some while and are fundamental
algorithms.
[Matt Caswell]
*) Make various cleanup routines no-ops and mark them as deprecated. Most
global cleanup functions are no longer required because they are handled
via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages).
Explicitly de-initing can cause problems (e.g. where a library that uses
OpenSSL de-inits, but an application is still using it). The affected
functions are CONF_modules_free(), ENGINE_cleanup(), OBJ_cleanup(),
EVP_cleanup(), BIO_sock_cleanup(), CRYPTO_cleanup_all_ex_data(),
RAND_cleanup(), SSL_COMP_free_compression_methods(), ERR_free_strings() and
COMP_zlib_cleanup().
[Matt Caswell]
*) --strict-warnings no longer enables runtime debugging options
such as REF_DEBUG. Instead, debug options are automatically
enabled with '--debug' builds.
[Andy Polyakov, Emilia Käsper]
*) Made DH and DH_METHOD opaque. The structures for managing DH objects
have been moved out of the public header files. New functions for managing
these have been added.
[Matt Caswell]
*) Made RSA and RSA_METHOD opaque. The structures for managing RSA
objects have been moved out of the public header files. New
functions for managing these have been added.
[Richard Levitte]
*) Made DSA and DSA_METHOD opaque. The structures for managing DSA objects
have been moved out of the public header files. New functions for managing
these have been added.
[Matt Caswell]
*) Made BIO and BIO_METHOD opaque. The structures for managing BIOs have been
moved out of the public header files. New functions for managing these
have been added.
[Matt Caswell]
*) Removed no-rijndael as a config option. Rijndael is an old name for AES.
*) Removed the mk1mf build scripts.
[Richard Levitte]
*) Headers are now wrapped, if necessary, with OPENSSL_NO_xxx, so
it is always safe to #include a header now.
[Rich Salz]
*) Removed the aged BC-32 config and all its supporting scripts
[Richard Levitte]
*) Added support for "pipelining". Ciphers that have the
EVP_CIPH_FLAG_PIPELINE flag set have a capability to process multiple
encryptions/decryptions simultaneously. There are currently no built-in
ciphers with this property but the expectation is that engines will be able
to offer it to significantly improve throughput. Support has been extended
into libssl so that multiple records for a single connection can be
processed in one go (for >=TLS 1.1).
[Matt Caswell]
*) Added the AFALG engine. This is an async capable engine which is able to
offload work to the Linux kernel. In this initial version it only supports
AES128-CBC. The kernel must be version 4.1.0 or greater.
[Catriona Lucey]
*) OpenSSL now uses a new threading API. It is no longer necessary to
set locking callbacks to use OpenSSL in a multi-threaded environment. There
are two supported threading models: pthreads and windows threads. It is
also possible to configure OpenSSL at compile time for "no-threads". The
old threading API should no longer be used. The functions have been
replaced with "no-op" compatibility macros.
[Alessandro Ghedini, Matt Caswell]
*) Modify behavior of ALPN to invoke callback after SNI/servername
callback, such that updates to the SSL_CTX affect ALPN.
[Todd Short]
*) Add SSL_CIPHER queries for authentication and key-exchange.
[Todd Short]
*) Changes to the DEFAULT cipherlist:
- Prefer (EC)DHE handshakes over plain RSA.
- Prefer AEAD ciphers over legacy ciphers.
- Prefer ECDSA over RSA when both certificates are available.
- Prefer TLSv1.2 ciphers/PRF.
- Remove DSS, SEED, IDEA, CAMELLIA, and AES-CCM from the
default cipherlist.
[Emilia Käsper]
*) Change the ECC default curve list to be this, in order: x25519,
secp256r1, secp521r1, secp384r1.
[Rich Salz]
*) RC4 based libssl ciphersuites are now classed as "weak" ciphers and are
disabled by default. They can be re-enabled using the
enable-weak-ssl-ciphers option to Configure.
[Matt Caswell]
*) If the server has ALPN configured, but supports no protocols that the
client advertises, send a fatal "no_application_protocol" alert.
This behaviour is SHALL in RFC 7301, though it isn't universally
implemented by other servers.
[Emilia Käsper]
*) Add X25519 support.
Integrate support for X25519 into EC library. This includes support
for public and private key encoding using the format documented in
draft-josefsson-pkix-newcurves-01: specifically X25519 uses the
OID from that draft, encodes public keys using little endian
format in the ECPoint structure and private keys using
little endian form in the privateKey field of the ECPrivateKey
structure. TLS support complies with draft-ietf-tls-rfc4492bis-06
and uses X25519(29).
Note: the current version supports key generation, public and
private key encoding and ECDH key agreement using the EC API.
Low level point operations such as EC_POINT_add(), EC_POINT_mul()
are NOT supported.
[Steve Henson]
*) Deprecate SRP_VBASE_get_by_user.
SRP_VBASE_get_by_user had inconsistent memory management behaviour.
In order to fix an unavoidable memory leak (CVE-2016-0798),
SRP_VBASE_get_by_user was changed to ignore the "fake user" SRP
seed, even if the seed is configured.
Users should use SRP_VBASE_get1_by_user instead. Note that in
SRP_VBASE_get1_by_user, caller must free the returned value. Note
also that even though configuring the SRP seed attempts to hide
invalid usernames by continuing the handshake with fake
credentials, this behaviour is not constant time and no strong
guarantees are made that the handshake is indistinguishable from
that of a valid user.
[Emilia Käsper]
*) Configuration change; it's now possible to build dynamic engines
without having to build shared libraries and vice versa. This
only applies to the engines in engines/, those in crypto/engine/
will always be built into libcrypto (i.e. "static").
Building dynamic engines is enabled by default; to disable, use
the configuration option "disable-dynamic-engine".
The only requirements for building dynamic engines are the
