Changes between 1.1.0h and 1.1.1 [xx XXX xxxx]
+ *) 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.
[Matthias St. Pierre]
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.
