Visual Studio 6 has not worked since.1.0 Rich Salz add err_clear_last_mark to allow callers to clear the last mark without clearing the errors. Richard levitte add "atfork" functions. If building on a system that without pthreads, see for application requirements. The rand facility now uses/requires this. Rich Salz add sha3. Andy polyakov the ui api becomes a permanent and integral part of libcrypto,.

Richard levitte added sha512/224 and sha512/256 algorithm support. Paul Dale the last traces of Netware support, first removed.1.0, have now been removed. Rich Salz get rid of ared, and in the process, make the processing of certain wood files (rc. Def/.map/.opt files produced from the ordinal files) more visible and hopefully easier to trace and debug (or make silent). Richard levitte make it possible to have environment variable assignments as arguments to config / Configure. Richard levitte add multi-prime rsa (rfc 8017) support. Paul Yang add SM3 implemented according to gb/t jack Lloyd, ronald Tse, erick borsboom add 'maximum Fragment Length' tls extension negotiation and support as documented in rfc6066. Based on a patch from Tomasz moń filipe raimundo da silva add SM4 implemented according to gb/T. jack Lloyd, ronald Tse, erick borsboom reimplement -newreq-nodes and err_error_string_n; the original author does not agree with the license change. Rich Salz add aria aead tls support. Jon Spillett some macro definitions to support VS6 have been removed.
O there is a public and private drbg instance. O the drbg instances writing are fork-safe. O keep all global drbg instances on the secure heap if it is enabled. O the public and private drbg instance are per thread for lock free operation paul Dale, benjamin Kaduk, kurt roeckx, rich Salz, matthias. Pierre changed Configure so it only says what it does and doesn't dump so much data. Instead,./ should be used as a script to display all sorts of configuration data. Richard levitte added processing of "make variables" to configure.
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 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.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 the default rand method makes use of a drbg.

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, statement 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 stones 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: note: In this pre-release of Openssl a draft version of the tlsv1.3 standard has been implemented.
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.
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.

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, apple cesar Pereida garcía, sohaib ul Hassan updated contributing rich Salz updated drbg / rand to request nonce and additional low entropy randomness from the system. 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.
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.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 pkcs8 container, wallpaper we now allow empty (zero character) pass phrases.
common archive. This allows to mitigate conflict between.0 and.1 side-by-side installations. It doesn't affect the way 3rd party applications are linked, only how multi-version installation is managed. Andy polyakov make ec_group_do_inverse_ord more robust and available to other ec cryptosystems, so that irrespective of BN_FLG_consttime, sca mitigations are applied to the fallback bn_mod_inverse. When using this function rather than BN_mod_inverse directly, new ec cryptosystem implementations are then safer-by-default. Billy bob Brumley 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 ecdsa and dsa signatures to protect against side channel attacks discovered by keegan ryan (ncc group).
Andy polyakov use the new ec_scalar_mul_ladder scaffold to implement a specialized ladder step for binary curves. The new implementation is based on formulas from differential addition-and-doubling in mixed Lopez-dahab projective coordinates, modified to independently blind the operands. Billy bob Brumley, sohaib ul Hassan, nicola tuveri add a scaffold to optionally enhance the montgomery ladder implementation for ec_scalar_mul_ladder (formerly ec_mul_consttime) allowing EC_methods list to implement their own specialized "ladder step to take advantage of more favorable coordinate systems or more efficient differential addition-and-doubling algorithms. Billy bob Brumley, sohaib ul Hassan, nicola tuveri modified the random device based seed sources to keep the relevant file descriptors open rather than reopening them on each access. This allows such sources to operate in a chroot jail without the associated device nodes being available. This behaviour can be controlled using paul Dale numerous side-channel attack mitigations have been applied. This may have performance impacts for some algorithms for the benefit of improved security.

When a release is created, that branch is forked off, and its changelog is also forked. For example, none of the changes business after.9.8n appear in the other logs, because.0.0 was created after that release and before.9.8o. Any changes that are merged across branches, however, should have an entry in each branch's changelog. This is the changelog for the master branch, the one that is currently in active development. The plain-text version of this document is available here: changelog. Txt, for other branches, the changelogs are distributed with the source, but are also available here: Table of contents, changes between.1.0h and.1.1 xx xxx xxxx revert blinding in ecdsa sign and instead make problematic addition length-invariant. Switch even to fixed-length Montgomery multiplication.
