NEWS ==== This file gives a brief overview of the major changes between each OpenSSL release. For more details please read the CHANGES file. OpenSSL Releases - - - - - OpenSSL 3.2 -- OpenSSL 3.2.0 is a feature release adding significant new functionality to OpenSSL. This release incorporates the following potentially significant or incompatible changes: The default SSL/TLS security level has been changed from 1 to 2. The `x509`, `ca`, and `req` apps now always produce X.509v3 certificates. Subject or issuer names in X.509 objects are now displayed as UTF-8 strings by default. This release adds the following new features: Support for client side QUIC, including support for multiple streams (RFC 9000) Support for Ed25519ctx, Ed25519ph and Ed448ph in addition to existing support for Ed25519 and Ed448 (RFC 8032) Support for deterministic ECDSA signatures (RFC 6979) Support for AES-GCM-SIV, a nonce-misuse-resistant AEAD (RFC 8452) Support for the Argon2 KDF, along with supporting thread pool functionality (RFC 9106) Support for Hybrid Public Key Encryption (HPKE) (RFC 9180) Support for SM4-XTS Support for Brainpool curves in TLS 1.3 Support for TLS Raw Public Keys (RFC 7250) Support for TCP Fast Open on Linux, macOS and FreeBSD, where enabled and supported (RFC 7413) Support for TLS certificate compression, including library support for zlib, Brotli and zstd (RFC 8879) Support for provider-based pluggable signature algorithms in TLS 1.3 with supporting CMS and X.509 functionality With a suitable provider this enables the use of post-quantum/quantum-safe cryptography. Support for using the Windows system certificate store as a source of trusted root certificates This is not yet enabled by default and must be activated using an environment variable. This is likely to become enabled by default in a future feature release. Support for using the IANA standard names in TLS ciphersuite configuration Multiple new features and improvements to CMP protocol support The following known issues are present in this release and will be rectified in a future release: Provider-based signature algorithms cannot be configured using the SignatureAlgorithms configuration file parameter (#22761) This release incorporates the following documentation enhancements: Added multiple tutorials on the OpenSSL library and in particular on writing various clients (using TLS and QUIC protocols) with libssl See [OpenSSL Guide]. A more detailed list of changes in this release can be found in the [CHANGES.md] file. Users interested in using the new QUIC functionality are encouraged to read the , which provides links to relevant documentation and example code. As always, bug reports and issues relating to OpenSSL can be [filed on our issue tracker][issue tracker].

Enhanced 'openssl list' with many new options. Added migration guide to man7. Implemented support for fully "pluggable" TLSv1.3 groups. Added support for Kernel TLS (KTLS). Changed the license to the Apache License v2.0. Moved all variations of the EVP ciphers CAST5, BF, IDEA, SEED, RC2, RC4, RC5, and DES to the legacy provider. Moved the EVP digests MD2, MD4, MDC2, WHIRLPOOL and RIPEMD-160 to the legacy provider. Added convenience functions for generating asymmetric key pairs. Deprecated the `OCSPREQCTX` type and functions.

The default security level for TLS is 1, so certificates signed using SHA1 are by default no longer trusted to authenticate servers or

enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly disabled; the project uses address sanitize/leak-detect instead. Added a Certificate Management Protocol (CMP, RFC 4210) implementation also covering CRMF (RFC 4211) and HTTP transfer (RFC 6712). It is part of the crypto lib and adds a 'cmp' app with a demo configuration. All widely used CMP features are supported for both clients and servers. Added a proper HTTP client supporting GET with optional redirection, POST, arbitrary request and response content types, TLS, persistent connections, connections via HTTP(s) proxies, connections and exchange via user-defined BIOs (allowing implicit connections), and timeout checks.

Supported KDFs are: HKDF, KBKDF, KRB5 KDF, PBKDF2, PKCS12 KDF, SCRYPT, SSH KDF, SSKDF, TLS1 PRF, X9.42 KDF and X9.63 KDF. All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224, SHA256, SHA384, SHA512 and Whirlpool digest functions have been deprecated. All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2, RC4, RC5 and SEED cipher functions have been deprecated. All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions have been deprecated. SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0, except when RSA key exchange without SHA1 is used.
