+
+ * The functions `OPENSSL_LH_stats` and `OPENSSL_LH_stats_bio` now only report
+ the `num_items`, `num_nodes` and `num_alloc_nodes` statistics. All other
+ statistics are no longer supported. For compatibility, these statistics are
+ still listed in the output but are now always reported as zero.

+
+### Changes between 3.0.1 and 3.0.2 [15 Mar 2022]
+
+ * Fixed a bug in the BN_mod_sqrt() function that can cause it to loop forever
+ for non-prime moduli.
+
+ Internally this function is used when parsing certificates that contain
+ elliptic curve public keys in compressed form or explicit elliptic curve
+ parameters with a base point encoded in compressed form.
+
+ It is possible to trigger the infinite loop by crafting a certificate that
+ has invalid explicit curve parameters.
+
+ Since certificate parsing happens prior to verification of the certificate
+ signature, any process that parses an externally supplied certificate may thus
+ be subject to a denial of service attack. The infinite loop can also be
+ reached when parsing crafted private keys as they can contain explicit
+ elliptic curve parameters.
+
+ Thus vulnerable situations include:
+
+ - TLS clients consuming server certificates
+ - TLS servers consuming client certificates
+ - Hosting providers taking certificates or private keys from customers
+ - Certificate authorities parsing certification requests from subscribers
+ - Anything else which parses ASN.1 elliptic curve parameters
+
+ Also any other applications that use the BN_mod_sqrt() where the attacker
+ can control the parameter values are vulnerable to this DoS issue.
+ ([CVE-2022-0778])

+ *Tomáš Mráz*
+
+ * Add ciphersuites based on DHE_PSK (RFC 4279) and ECDHE_PSK (RFC 5489)
+ to the list of ciphersuites providing Perfect Forward Secrecy as
+ required by SECLEVEL >= 3.
+
+ *Dmitry Belyavskiy, Nicola Tuveri*
+
+ * Made the AES constant time code for no-asm configurations
+ optional due to the resulting 95% performance degradation.
+ The AES constant time code can be enabled, for no assembly
+ builds, with: ./config no-asm -DOPENSSL_AES_CONST_TIME
+
+ *Paul Dale*
+
+ * Fixed PEM_write_bio_PKCS8PrivateKey() to make it possible to use empty
+ passphrase strings.
+
+ *Darshan Sen*
+
+ * The negative return value handling of the certificate verification callback
+ was reverted. The replacement is to set the verification retry state with
+ the SSL_set_retry_verify() function.
+
+ *Tomáš Mráz*
+
+### Changes between 3.0.0 and 3.0.1 [14 Dec 2021]
+
+ * Fixed invalid handling of X509_verify_cert() internal errors in libssl
+ Internally libssl in OpenSSL calls X509_verify_cert() on the client side to
+ verify a certificate supplied by a server. That function may return a
+ negative return value to indicate an internal error (for example out of
+ memory). Such a negative return value is mishandled by OpenSSL and will cause
+ an IO function (such as SSL_connect() or SSL_do_handshake()) to not indicate
+ success and a subsequent call to SSL_get_error() to return the value
+ SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be
+ returned by OpenSSL if the application has previously called
+ SSL_CTX_set_cert_verify_callback(). Since most applications do not do this
+ the SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be
+ totally unexpected and applications may not behave correctly as a result. The
+ exact behaviour will depend on the application but it could result in
+ crashes, infinite loops or other similar incorrect responses.
+
+ This issue is made more serious in combination with a separate bug in OpenSSL
+ 3.0 that will cause X509_verify_cert() to indicate an internal error when
+ processing a certificate chain. This will occur where a certificate does not
+ include the Subject Alternative Name extension but where a Certificate
+ Authority has enforced name constraints. This issue can occur even with valid
+ chains.
+ ([CVE-2021-4044])
+
+ *Matt Caswell*
+
+ * Corrected a few file name and file reference bugs in the build,
+ installation and setup scripts, which lead to installation verification
+ failures. Slightly enhanced the installation verification script.
+
+ *Richard Levitte*
+
+ * Fixed EVP_PKEY_eq() to make it possible to use it with strictly private
+ keys.
+
+ *Richard Levitte*
+
+ * Fixed PVK encoder to properly query for the passphrase.
+
+ *Tomáš Mráz*
+
+ * Multiple fixes in the OSSL_HTTP API functions.
+
+ *David von Oheimb*
+
+ * Allow sign extension in OSSL_PARAM_allocate_from_text() for the
+ OSSL_PARAM_INTEGER data type and return error on negative numbers
+ used with the OSSL_PARAM_UNSIGNED_INTEGER data type. Make
+ OSSL_PARAM_BLD_push_BN{,_pad}() return an error on negative numbers.
+
+ *Richard Levitte*
+
+ * Allow copying uninitialized digest contexts with EVP_MD_CTX_copy_ex.
+

+
+ * Fixed detection of ARMv7 and ARM64 CPU features on FreeBSD.
+
+ *Allan Jude*
+
+ * Multiple threading fixes.
+
+ *Matt Caswell*
+
+ * Added NULL digest implementation to keep compatibility with 1.1.1 version.
+
+ *Tomáš Mráz*
+
+ * Allow fetching an operation from the provider that owns an unexportable key
+ as a fallback if that is still allowed by the property query.
+
+ *Richard Levitte*
+
+### Changes between 1.1.1 and 3.0.0 [7 sep 2021]
+
+ * TLS_MAX_VERSION, DTLS_MAX_VERSION and DTLS_MIN_VERSION constants are now
+ deprecated.
+
+ *Matt Caswell*
+
+ * The `OPENSSL_s390xcap` environment variable can be used to set bits in the
+ S390X capability vector to zero. This simplifies testing of different code
+ paths on S390X architecture.
+
+ *Patrick Steuer*
+
+ * Encrypting more than 2^64 TLS records with AES-GCM is disallowed
+ as per FIPS 140-2 IG A.5 "Key/IV Pair Uniqueness Requirements from
+ SP 800-38D". The communication will fail at this point.
+
+ *Paul Dale*
+
+ * The EC_GROUP_clear_free() function is deprecated as there is nothing
+ confidential in EC_GROUP data.
+
+ *Nicola Tuveri*
+
+ * The byte order mark (BOM) character is ignored if encountered at the
+ beginning of a PEM-formatted file.
+
+ *Dmitry Belyavskiy*
+
+ * Added CMS support for the Russian GOST algorithms.
+
+ *Dmitry Belyavskiy*
* Due to move of the implementation of cryptographic operations
to the providers, validation of various operation parameters can
*Richard Levitte*
+ * Added various `_ex` functions to the OpenSSL API that support using
+ a non-default `OSSL_LIB_CTX`.
+
+ *OpenSSL team*
+
* Handshake now fails if Extended Master Secret extension is dropped
on renegotiation.
*Rich Salz*
- * Introduced a new method type and API, OSSL_ENCODER, to
- represent generic encoders.
+ * Introduced a new method type and API, OSSL_ENCODER, to represent
+ generic encoders. These do the same sort of job that PEM writers
+ and d2i functions do, but with support for methods supplied by
+ providers, and the possibility for providers to support other
+ formats as well.
+
+ *Richard Levitte*
+
+ * Introduced a new method type and API, OSSL_DECODER, to represent
+ generic decoders. These do the same sort of job that PEM readers
+ and i2d functions do, but with support for methods supplied by
+ providers, and the possibility for providers to support other
+ formats as well.

*Shane Lontis*
- * Add KMAC to EVP_MAC.
+ * Added KMAC to EVP_MAC.
*Shane Lontis*
*Raja Ashok*
+ * Added a new concept for OpenSSL plugability: providers. This
+ functionality is designed to replace the ENGINE API and ENGINE
+ implementations, and to be much more dynamic, allowing provider
+ authors to introduce new algorithms among other things, as long as
+ there's an API that supports the algorithm type.
+
+ With this concept comes a new core API for interaction between
+ libcrypto and provider implementations. Public libcrypto functions
+ that want to use providers do so through this core API.
+
+ The main documentation for this core API is found in
+ doc/man7/provider.pod, doc/man7/provider-base.pod, and they in turn
+ refer to other manuals describing the API specific for supported
+ algorithm types (also called operations).
