+ Changes between 1.1.0h and 1.1.1 [xx XXX xxxx]
+ *) Add coordinate blinding for EC_POINT and implement projective
+ coordinate blinding for generic prime curves as a countermeasure to
+ chosen point SCA attacks.
+ [Sohaib ul Hassan, Nicola Tuveri, Billy Bob Brumley]
+
+ *) Add blinding to an ECDSA signature to protect against side channel attacks
+ discovered by Keegan Ryan (NCC Group).
+ [Matt Caswell]
+
+ *) Enforce checking in the pkeyutl command line app to ensure that the input
+ length does not exceed the maximum supported digest length when performing
+ a sign, verify or verifyrecover operation.
+ [Matt Caswell]
+
+ *) SSL_MODE_AUTO_RETRY is enabled by default. Applications that use blocking
+ I/O in combination with something like select() or poll() will hang. This
+ can be turned off again using SSL_CTX_clear_mode().
+ Many applications do not properly handle non-application data records, and
+ TLS 1.3 sends more of such records. Setting SSL_MODE_AUTO_RETRY works
+ around the problems in those applications, but can also break some.
+ It's recommended to read the manpages about SSL_read(), SSL_write(),
+ SSL_get_error(), SSL_shutdown(), SSL_CTX_set_mode() and
+ SSL_CTX_set_read_ahead() again.
+ [Kurt Roeckx]
+
+ *) When unlocking a pass phrase protected PEM file or PKCS#8 container, we
+ now allow empty (zero character) pass phrases.
+ [Richard Levitte]
+
+ *) Apply blinding to binary field modular inversion and remove patent
+ pending (OPENSSL_SUN_GF2M_DIV) BN_GF2m_mod_div implementation.
+ [Billy Bob Brumley]
+
+ *) Deprecate ec2_mult.c and unify scalar multiplication code paths for
+ binary and prime elliptic curves.
+ [Billy Bob Brumley]
+
+ *) Remove ECDSA nonce padding: EC_POINT_mul is now responsible for
+ constant time fixed point multiplication.
+ [Billy Bob Brumley]
+
+ *) Revise elliptic curve scalar multiplication with timing attack
+ defenses: ec_wNAF_mul redirects to a constant time implementation
+ when computing fixed point and variable point multiplication (which
+ in OpenSSL are mostly used with secret scalars in keygen, sign,
+ ECDH derive operations).
+ [Billy Bob Brumley, Nicola Tuveri, Cesar Pereida GarcĂa,
+ Sohaib ul Hassan]
+
+ *) Updated CONTRIBUTING
+ [Rich Salz]
+
+ *) Updated DRBG / RAND to request nonce and additional low entropy
+ randomness from the system.
+ [Matthias St. Pierre]
+
+ *) Updated 'openssl rehash' to use OpenSSL consistent default.
+ [Richard Levitte]
+
+ *) Moved the load of the ssl_conf module to libcrypto, which helps
+ loading engines that libssl uses before libssl is initialised.
+ [Matt Caswell]
+
+ *) Added EVP_PKEY_sign() and EVP_PKEY_verify() for EdDSA
+ [Matt Caswell]
+
+ *) Fixed X509_NAME_ENTRY_set to get multi-valued RDNs right in all cases.
+ [Ingo Schwarze, Rich Salz]
+
+ *) Added output of accepting IP address and port for 'openssl s_server'
+ [Richard Levitte]
+
+ *) Added a new API for TLSv1.3 ciphersuites:
+ SSL_CTX_set_ciphersuites()
+ SSL_set_ciphersuites()
+ [Matt Caswell]
+
+ *) Memory allocation failures consistenly add an error to the error
+ stack.
+ [Rich Salz]
+
+ *) Don't use OPENSSL_ENGINES and OPENSSL_CONF environment values
+ in libcrypto when run as setuid/setgid.
+ [Bernd Edlinger]
+
+ *) Load any config file by default when libssl is used.
+ [Matt Caswell]
+
+ *) Added new public header file <openssl/rand_drbg.h> and documentation
+ for the RAND_DRBG API. See manual page RAND_DRBG(7) for an overview.
+ [Matthias St. Pierre]
+
+ *) QNX support removed (cannot find contributors to get their approval
+ for the license change).
+ [Rich Salz]
+
+ *) TLSv1.3 replay protection for early data has been implemented. See the
+ SSL_read_early_data() man page for further details.
+ [Matt Caswell]
+
+ *) Separated TLSv1.3 ciphersuite configuration out from TLSv1.2 ciphersuite
+ configuration. TLSv1.3 ciphersuites are not compatible with TLSv1.2 and
+ below. Similarly TLSv1.2 ciphersuites are not compatible with TLSv1.3.
+ In order to avoid issues where legacy TLSv1.2 ciphersuite configuration
+ would otherwise inadvertently disable all TLSv1.3 ciphersuites the
+ configuration has been separated out. See the ciphers man page or the
+ SSL_CTX_set_ciphersuites() man page for more information.
+ [Matt Caswell]
+
+ *) On POSIX (BSD, Linux, ...) systems the ocsp(1) command running
+ in responder mode now supports the new "-multi" option, which
+ spawns the specified number of child processes to handle OCSP
+ requests. The "-timeout" option now also limits the OCSP
+ responder's patience to wait to receive the full client request
+ on a newly accepted connection. Child processes are respawned
+ as needed, and the CA index file is automatically reloaded
+ when changed. This makes it possible to run the "ocsp" responder
+ as a long-running service, making the OpenSSL CA somewhat more
+ feature-complete. In this mode, most diagnostic messages logged
+ after entering the event loop are logged via syslog(3) rather than
+ written to stderr.
+ [Viktor Dukhovni]
+
+ *) Added support for X448 and Ed448. Heavily based on original work by
+ Mike Hamburg.
+ [Matt Caswell]
+
+ *) Extend OSSL_STORE with capabilities to search and to narrow the set of
+ objects loaded. This adds the functions OSSL_STORE_expect() and
+ OSSL_STORE_find() as well as needed tools to construct searches and
+ get the search data out of them.
+ [Richard Levitte]
+
+ *) Support for TLSv1.3 added. Note that users upgrading from an earlier
+ version of OpenSSL should review their configuration settings to ensure
+ that they are still appropriate for TLSv1.3. For further information see:
+ https://www.openssl.org/blog/blog/2018/02/08/tlsv1.3/
+
+ NOTE: In this pre-release of OpenSSL a draft version of the
+ TLSv1.3 standard has been implemented. Implementations of different draft
+ versions of the standard do not inter-operate, and this version will not
+ inter-operate with an implementation of the final standard when it is
+ eventually published. Different pre-release versions may implement
+ different versions of the draft. The final version of OpenSSL 1.1.1 will
+ implement the final version of the standard.
+ TODO(TLS1.3): Remove the above note before final release
+ [Matt Caswell]
+
+ *) Grand redesign of the OpenSSL random generator
+
+ The default RAND method now utilizes an AES-CTR DRBG according to
+ NIST standard SP 800-90Ar1. The new random generator is essentially
+ a port of the default random generator from the OpenSSL FIPS 2.0
+ object module. It is a hybrid deterministic random bit generator
+ using an AES-CTR bit stream and which seeds and reseeds itself
+ automatically using trusted system entropy sources.
+
+ Some of its new features are:
+ o Support for multiple DRBG instances with seed chaining.
+ o Add a public DRBG instance for the default RAND method.
+ o Add a dedicated DRBG instance for generating long term private keys.
+ o Make the DRBG instances fork-safe.
+ o Keep all global DRBG instances on the secure heap if it is enabled.
+ o Add a DRBG instance to every SSL instance for lock free operation
+ and to increase unpredictability.
+ [Paul Dale, Benjamin Kaduk, Kurt Roeckx, Rich Salz, Matthias St. Pierre]
+
+ *) Changed Configure so it only says what it does and doesn't dump
+ so much data. Instead, ./configdata.pm should be used as a script
+ to display all sorts of configuration data.
