- Changes between 1.1.1 and 1.1.2 [xx XXX xxxx]
+ Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
+
+ *) Added EVP_KDF, an EVP layer KDF API, to simplify adding KDF and PRF
+ implementations. This includes an EVP_PKEY to EVP_KDF bridge for
+ those algorithms that were already supported through the EVP_PKEY API
+ (scrypt, TLS1 PRF and HKDF). The low-level KDF functions for PBKDF2
+ and scrypt are now wrappers that call EVP_KDF.
+ [David Makepeace]
+
+ *) Build devcrypto engine as a dynamic engine.
+ [Eneas U de Queiroz]
+
+ *) Add keyed BLAKE2 to EVP_MAC.
+ [Antoine Salon]
+
+ *) Fix a bug in the computation of the endpoint-pair shared secret used
+ by DTLS over SCTP. This breaks interoperability with older versions
+ of OpenSSL like OpenSSL 1.1.0 and OpenSSL 1.0.2. There is a runtime
+ switch SSL_MODE_DTLS_SCTP_LABEL_LENGTH_BUG (off by default) enabling
+ interoperability with such broken implementations. However, enabling
+ this switch breaks interoperability with correct implementations.
+
+ *) Fix a use after free bug in d2i_X509_PUBKEY when overwriting a
+ re-used X509_PUBKEY object if the second PUBKEY is malformed.
+ [Bernd Edlinger]
+
+ *) Move strictness check from EVP_PKEY_asn1_new() to EVP_PKEY_asn1_add0().
+ [Richard Levitte]
+
+ *) Change the license to the Apache License v2.0.
+ [Richard Levitte]
+
+ *) Change the possible version information given with OPENSSL_API_COMPAT.
+ It may be a pre-3.0.0 style numerical version number as it was defined
+ in 1.1.0, and it may also simply take the major version number.
+
+ Because of the version numbering of pre-3.0.0 releases, the values 0,
+ 1 and 2 are equivalent to 0x00908000L (0.9.8), 0x10000000L (1.0.0) and
+ 0x10100000L (1.1.0), respectively.
+ [Richard Levitte]
+
+ *) Switch to a new version scheme using three numbers MAJOR.MINOR.PATCH.
+
+ o Major releases (indicated by incrementing the MAJOR release number)
+ may introduce incompatible API/ABI changes.
+ o Minor releases (indicated by incrementing the MINOR release number)
+ may introduce new features but retain API/ABI compatibility.
+ o Patch releases (indicated by incrementing the PATCH number)
+ are intended for bug fixes and other improvements of existing
+ features only (like improving performance or adding documentation)
+ and retain API/ABI compatibility.
+ [Richard Levitte]
+
+ *) Add support for RFC5297 SIV mode (siv128), including AES-SIV.
+ [Todd Short]
+
+ *) Remove the 'dist' target and add a tarball building script. The
+ 'dist' target has fallen out of use, and it shouldn't be
+ necessary to configure just to create a source distribution.
+ [Richard Levitte]
+
+ *) Recreate the OS390-Unix config target. It no longer relies on a
+ special script like it did for OpenSSL pre-1.1.0.
+ [Richard Levitte]
+
+ *) Instead of having the source directories listed in Configure, add
+ a 'build.info' keyword SUBDIRS to indicate what sub-directories to
+ look into.
+ [Richard Levitte]
+
+ *) Add GMAC to EVP_MAC.
+ [Paul Dale]
+
+ *) Ported the HMAC, CMAC and SipHash EVP_PKEY_METHODs to EVP_MAC.
+ [Richard Levitte]
+
+ *) Added EVP_MAC, an EVP layer MAC API, to simplify adding MAC
+ implementations. This includes a generic EVP_PKEY to EVP_MAC bridge,
+ to facilitate the continued use of MACs through raw private keys in
+ functionality such as EVP_DigestSign* and EVP_DigestVerify*.
+ [Richard Levitte]
+
+ *) Deprecate ECDH_KDF_X9_62() and mark its replacement as internal. Users
+ should use the EVP interface instead (EVP_PKEY_CTX_set_ecdh_kdf_type).
+ [Antoine Salon]
+
+ *) Added EVP_PKEY_ECDH_KDF_X9_63 and ecdh_KDF_X9_63() as replacements for
+ the EVP_PKEY_ECDH_KDF_X9_62 KDF type and ECDH_KDF_X9_62(). The old names
+ are retained for backwards compatibility.
+ [Antoine Salon]
*) AES-XTS mode now enforces that its two keys are different to mitigate
the attacked described in "Efficient Instantiations of Tweakable
list of built in objects, i.e. OIDs with names.
[Richard Levitte]
+ *) Added support for Linux Kernel TLS data-path. The Linux Kernel data-path
+ improves application performance by removing data copies and providing
+ applications with zero-copy system calls such as sendfile and splice.
+ [Boris Pismenny]
+
+ Changes between 1.1.1a and 1.1.1b [xx XXX xxxx]
+
+ *) Change the info callback signals for the start and end of a post-handshake
+ message exchange in TLSv1.3. In 1.1.1/1.1.1a we used SSL_CB_HANDSHAKE_START
+ and SSL_CB_HANDSHAKE_DONE. Experience has shown that many applications get
+ confused by this and assume that a TLSv1.2 renegotiation has started. This
+ can break KeyUpdate handling. Instead we no longer signal the start and end
+ of a post handshake message exchange (although the messages themselves are
+ still signalled). This could break some applications that were expecting
+ the old signals. However without this KeyUpdate is not usable for many
+ applications.
+ [Matt Caswell]
+
+ Changes between 1.1.1 and 1.1.1a [20 Nov 2018]
+
+ *) Timing vulnerability in DSA signature generation
+
+ The OpenSSL DSA signature algorithm has been shown to be vulnerable to a
+ timing side channel attack. An attacker could use variations in the signing
+ algorithm to recover the private key.
+
+ This issue was reported to OpenSSL on 16th October 2018 by Samuel Weiser.
+ (CVE-2018-0734)
+ [Paul Dale]
+
+ *) Timing vulnerability in ECDSA signature generation
+
+ The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a
+ timing side channel attack. An attacker could use variations in the signing
+ algorithm to recover the private key.
+
+ This issue was reported to OpenSSL on 25th October 2018 by Samuel Weiser.
+ (CVE-2018-0735)
+ [Paul Dale]
+
+ *) Fixed the issue that RAND_add()/RAND_seed() silently discards random input
+ if its length exceeds 4096 bytes. The limit has been raised to a buffer size
+ of two gigabytes and the error handling improved.
+
+ This issue was reported to OpenSSL by Dr. Falko Strenzke. It has been
+ categorized as a normal bug, not a security issue, because the DRBG reseeds
+ automatically and is fully functional even without additional randomness
+ provided by the application.
+
Changes between 1.1.0i and 1.1.1 [11 Sep 2018]
*) Add a new ClientHello callback. Provides a callback interface that gives
(still largely untested)
[Bodo Moeller]
- *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
+ *) New function ASN1_tag2str() to convert an ASN1 tag to a descriptive
ASCII string. This was handled independently in various places before.
[Steve Henson]
*) A minor bug in ssl/s3_clnt.c where there would always be 4 0
bytes sent in the client random.
