- Changes between 1.1.0g and 1.1.1 [xx XXX xxxx]
+ Changes between 1.1.0h and 1.1.1 [xx XXX xxxx]
+
+ *) Change generating and checking of primes so that the error rate of not
+ being prime depends on the intended use based on the size of the input.
+ For larger primes this will result in more rounds of Miller-Rabin.
+ The maximal error rate for primes with more than 1080 bits is lowered
+ to 2^-128.
+ [Kurt Roeckx, Annie Yousar]
+
+ *) Increase the number of Miller-Rabin rounds for DSA key generating to 64.
+ [Kurt Roeckx]
+
+ *) The 'tsget' script is renamed to 'tsget.pl', to avoid confusion when
+ moving between systems, and to avoid confusion when a Windows build is
+ done with mingw vs with MSVC. For POSIX installs, there's still a
+ symlink or copy named 'tsget' to avoid that confusion as well.
+ [Richard Levitte]
+
+ *) Revert blinding in ECDSA sign and instead make problematic addition
+ length-invariant. Switch even to fixed-length Montgomery multiplication.
+ [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 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 RAND_keep_random_devices_open().
+ [Paul Dale]
+
+ *) Numerous side-channel attack mitigations have been applied. This may have
+ performance impacts for some algorithms for the benefit of improved
+ security. Specific changes are noted in this change log by their respective
+ authors.
+ [Matt Caswell]
+
+ *) AIX shared library support overhaul. Switch to AIX "natural" way of
+ handling shared libraries, which means collecting shared objects of
+ different versions and bitnesses in one common archive. This allows to
+ mitigate conflict between 1.0 and 1.1 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).
+ [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 García,
+ 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.
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
- configuraton has been separated out. See the ciphers man page or the
+ configuration has been separated out. See the ciphers man page or the
SSL_CTX_set_ciphersuites() man page for more information.
[Matt Caswell]
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 The default RAND method makes use of a DRBG.
+ o There is a public and private DRBG instance.
+ o The DRBG instances are 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.
+ o The public and private DRBG instance are per thread for lock free
+ operation

*) Changed Configure so it only says what it does and doesn't dump
issues, has been replaced to always returns NULL.

- Changes between 1.1.0g and 1.1.0h [xx XXX xxxx]
+
+ Changes between 1.1.0h and 1.1.0i [xx XXX xxxx]
+
+ *) Fixed a text canonicalisation bug in CMS
+
+ Where a CMS detached signature is used with text content the text goes
+ through a canonicalisation process first prior to signing or verifying a
+ signature. This process strips trailing space at the end of lines, converts
+ line terminators to CRLF and removes additional trailing line terminators
+ at the end of a file. A bug in the canonicalisation process meant that
+ some characters, such as form-feed, were incorrectly treated as whitespace
+ and removed. This is contrary to the specification (RFC5485). This fix
+ could mean that detached text data signed with an earlier version of
+ OpenSSL 1.1.0 may fail to verify using the fixed version, or text data
+ signed with a fixed OpenSSL may fail to verify with an earlier version of
+ OpenSSL 1.1.0. A workaround is to only verify the canonicalised text data
+ and use the "-binary" flag (for the "cms" command line application) or set
+ the SMIME_BINARY/PKCS7_BINARY/CMS_BINARY flags (if using CMS_verify()).
+ [Matt Caswell]

+ Changes between 1.1.0g and 1.1.0h [27 Mar 2018]
*) Constructed ASN.1 types with a recursive definition could exceed the stack
