OpenSSL 3.0

### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0.0 [7 sep 2021]

  • Enhanced 'openssl list' with many new options.
  • Added migration guide to man7.
  • Implemented support for fully "pluggable" TLSv1.3 groups.
  • Added suport 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 OCSP_REQ_CTX type and functions.
  • Deprecated the EC_KEY and EC_KEY_METHOD types and functions.
  • Deprecated the RSA and RSA_METHOD types and functions.
  • Deprecated the DSA and DSA_METHOD types and functions.
  • Deprecated the DH and DH_METHOD types and functions.
  • Deprecated the ERR_load_ functions.
  • Remove the RAND_DRBG API.
  • Deprecated the ENGINE API.
  • Added OSSL_LIB_CTX, a libcrypto library context.
  • Added various _ex functions to the OpenSSL API that support using a non-default OSSL_LIB_CTX.
  • Interactive mode is removed from the 'openssl' program.
  • The X25519, X448, Ed25519, Ed448, SHAKE128 and SHAKE256 algorithms are included in the FIPS provider.
  • X509 certificates signed using SHA1 are no longer allowed at security level 1 or higher. The default security level for TLS is 1, so certificates signed using SHA1 are by default no longer trusted to authenticate servers or clients.
  • 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.
  • Added util/ for checking adherence to the coding guidelines.
  • Added OSSL_ENCODER, a generic encoder API.
  • Added OSSL_DECODER, a generic decoder API.
  • Added OSSL_PARAM_BLD, an easier to use API to OSSL_PARAM.
  • Added error raising macros, ERR_raise() and ERR_raise_data().
  • Deprecated ERR_put_error(), ERR_get_error_line(), ERR_get_error_line_data(), ERR_peek_error_line_data(), ERR_peek_last_error_line_data() and ERR_func_error_string().
  • Added OSSL_PROVIDER_available(), to check provider availibility.
  • Added 'openssl mac' that uses the EVP_MAC API.
  • Added 'openssl kdf' that uses the EVP_KDF API.
  • Add OPENSSL_info() and 'openssl info' to get built-in data.
  • Add support for enabling instrumentation through trace and debug output.
  • Changed our version number scheme and set the next major release to 3.0.0
  • Added EVP_MAC, an EVP layer MAC API, and a generic EVP_PKEY to EVP_MAC bridge. Supported MACs are: BLAKE2, CMAC, GMAC, HMAC, KMAC, POLY1305and SIPHASH.
  • Removed the heartbeat message in DTLS feature.
  • Added EVP_KDF, an EVP layer KDF and PRF API, and a generic EVP_PKEY to EVP_KDF bridge. 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.
  • Added providers, a new pluggability concept that will replace the ENGINE API and ENGINE implementations.

They also say (reformatted to not be on a silly superlong line)

Most applications that worked with OpenSSL 1.1.1 will still work
unchanged and will simply need to be recompiled (although you may
see numerous compilation warnings about using deprecated APIs).

Some applications may need to make changes to compile and work
correctly, and many applications will need to be changed to avoid
the deprecations warnings. We have put together a migration guide
to describe the major differences in OpenSSL 3.0 compared to
previous releases.

In other words, for anyone upgrading an existing (BLFS) system you will need to recompile everything which links to openssl before you can discard the currently-installed 1.1.1.

Besides the afalg failure (we've documented in the book), 80-test_cmp_http.t also fails:

Below is a list of packages I've rebuilt with OpenSSL-3.0.0 (updating):

Now openssl-1.1 libs is moved out from /usr/lib on my system.

Fedora will be documenting which of their packages have problems in
