OpenSSL Releases

OpenSSL 3.0
-----------
-### Changes between 1.1.1 and 3.0 [xx XXX xxxx] ###
+### Changes between 1.1.1 and 3.0 [xx XXX xxxx]
+
+ * 'Configure' has been changed to figure out the configuration target if
+ none is given on the command line. Consequently, the 'config' script is
+ now only a mere wrapper. All documentation is changed to only mention
+ 'Configure'.
+
+ *Rich Salz and Richard Levitte*
+
+ * Added a library context that applications as well as other
+ libraries can use to form a separate context within which libcrypto
+ operations are performed.
+
+ There are two ways this can be used:
+
+ - Directly, by passing a library context to functions that take
+ such an argument, such as `EVP_CIPHER_fetch` and similar algorithm
+ fetching functions.
+ - Indirectly, by creating a new library context and then assigning
+ it as the new default, with `OPENSSL_CTX_set0_default`.
+
+ All public OpenSSL functions that take an `OPENSSL_CTX` pointer,
+ apart from the functions directly related to `OPENSSL_CTX`, accept
+ NULL to indicate that the default library context should be used.
+
+ Library code that changes the default library context using
+ `OPENSSL_CTX_set0_default` should take care to restore it with a
+ second call before returning to the caller.
+
+ *Richard Levitte*
+
+ * Handshake now fails if Extended Master Secret extension is dropped
+ on renegotiation.
+
+ *Tomas Mraz*
+
+ * Dropped interactive mode from the 'openssl' program. From now on,
+ the `openssl` command without arguments is equivalent to `openssl
+ help`.
+
+ *Richard Levitte*
+
+ * Renamed EVP_PKEY_cmp() to EVP_PKEY_eq() and
+ EVP_PKEY_cmp_parameters() to EVP_PKEY_parameters_eq().
+ While the old function names have been retained for backward compatibility
+ they should not be used in new developments
+ because their return values are confusing: Unlike other `_cmp()` functions
+ they do not return 0 in case their arguments are equal.
+
+ *David von Oheimb*
+
+ * Deprecated EC_METHOD_get_field_type(). Applications should switch to
+ EC_GROUP_get_field_type().
+
+ *Billy Bob Brumley*
+
+ * Deprecated EC_GFp_simple_method(), EC_GFp_mont_method(),
+ EC_GF2m_simple_method(), EC_GFp_nist_method(), EC_GFp_nistp224_method()
+ EC_GFp_nistp256_method(), and EC_GFp_nistp521_method().
+ Applications should rely on the library automatically assigning a suitable
+ EC_METHOD internally upon EC_GROUP construction.
+
+ *Billy Bob Brumley*
+
+ * Deprecated EC_GROUP_new(), EC_GROUP_method_of(), and EC_POINT_method_of().
+ EC_METHOD is now an internal-only concept and a suitable EC_METHOD is
+ assigned internally without application intervention.
+ Users of EC_GROUP_new() should switch to a different suitable constructor.
+
+ *Billy Bob Brumley*
+
+ * Add CAdES-BES signature verification support, mostly derived
+ from ESSCertIDv2 TS (RFC 5816) contribution by Marek Klein.
+
+ *Filipe Raimundo da Silva*
+
+ * Add CAdES-BES signature scheme and attributes support (RFC 5126) to CMS API.
+
+ *Antonio Iacono*
+
+ * Deprecated EC_POINT_make_affine() and EC_POINTs_make_affine(). These
+ functions are not widely used and now OpenSSL automatically perform this
+ conversion when needed.
+
+ *Billy Bob Brumley*
+
+ * Deprecated EC_GROUP_precompute_mult(), EC_GROUP_have_precompute_mult(), and
+ EC_KEY_precompute_mult(). These functions are not widely used and
+ applications should instead switch to named curves which OpenSSL has
+ hardcoded lookup tables for.
+
+ *Billy Bob Brumley*
+
+ * Deprecated EC_POINTs_mul(). This function is not widely used and applications
+ should instead use the L<EC_POINT_mul(3)> function.
+
+ *Billy Bob Brumley*
+
+ * Removed FIPS_mode() and FIPS_mode_set(). These functions are legacy API's
+ that are not applicable to the new provider model. Applications should
+ instead use EVP_default_properties_is_fips_enabled() and
+ EVP_default_properties_enable_fips().
+
+ *Shane Lontis*
+
+ * The SSL option SSL_OP_IGNORE_UNEXPECTED_EOF is introduced. If that option
+ is set, an unexpected EOF is ignored, it pretends a close notify was received
+ instead and so the returned error becomes SSL_ERROR_ZERO_RETURN.
+
+ *Dmitry Belyavskiy*
+
+ * Deprecated EC_POINT_set_Jprojective_coordinates_GFp() and
+ EC_POINT_get_Jprojective_coordinates_GFp(). These functions are not widely
+ used and applications should instead use the
+ L<EC_POINT_set_affine_coordinates(3)> and
+ L<EC_POINT_get_affine_coordinates(3)> functions.
+
+ *Billy Bob Brumley*
* Added OSSL_PARAM_BLD to the public interface. This allows OSSL_PARAM
arrays to be more easily constructed via a series of utility functions.
*Paul Dale*
+ * The security strength of SHA1 and MD5 based signatures in TLS has been
+ reduced. This results in SSL 3, TLS 1.0, TLS 1.1 and DTLS 1.0 no longer
+ working at the default security level of 1 and instead requires security
+ level 0. The security level can be changed either using the cipher string
+ with @SECLEVEL, or calling SSL_CTX_set_security_level().
+
+ *Kurt Roeckx*
+
* EVP_PKEY_get0_RSA(), EVP_PKEY_get0_DSA(), EVP_PKEY_get0_DH(), and
EVP_PKEY_get0_EC_KEY() can now handle EVP_PKEYs with provider side
internal keys, if they correspond to one of those built in types.
*Matthias St. Pierre*
-
* The test suite is changed to preserve results of each test recipe.
A new directory test-runs/ with subdirectories named like the
test recipes are created in the build tree for this purpose.
*Richard Levitte*
- * The command line utilities ecparam and ec have been deprecated. Instead
- use the pkeyparam, pkey and genpkey programs.
+ * Added an implementation of CMP and CRMF (RFC 4210, RFC 4211 RFC 6712).
+ This adds crypto/cmp/, crpyto/crmf/, apps/cmp.c, and test/cmp_*.
+ See L<openssl-cmp(1)> and L<OSSL_CMP_exec_IR_ses(3)> as starting points.
- *Paul Dale*
+ *David von Oheimb, Martin Peylo*
+
+ * Generalized the HTTP client code from crypto/ocsp/ into crpyto/http/.
+ The legacy OCSP-focused and only partly documented API is retained.
+ See L<OSSL_CMP_MSG_http_perform(3)> etc. for details.
+
+ *David von Oheimb*
+
+ * BIO_do_connect and BIO_do_handshake have been extended:
+ If domain name resolution yields multiple IP addresses all of them are tried
+ after connect() failures.
+
+ *David von Oheimb*

*Richard Levitte*
* For built-in EC curves, ensure an EC_GROUP built from the curve name is
when primes for RSA keys are computed.
Since we previously always generated primes == 2 (mod 3) for RSA keys,
the 2-prime and 3-prime RSA modules were easy to distinguish, since
- N = p*q = 1 (mod 3), but N = p*q*r = 2 (mod 3). Therefore fingerprinting
+ `N = p*q = 1 (mod 3)`, but `N = p*q*r = 2 (mod 3)`. Therefore fingerprinting
2-prime vs. 3-prime RSA keys was possible by computing N mod 3.
This avoids possible fingerprinting of newly generated RSA modules.
