      OpenSSL 3.0.0-alpha1 was releases about a week ago. OpenSSL 1.1.x APIs are still functional. However some APIs have been deprecated and FIPS (usedforsecurity flag) is no longer functional.

      • One shot HMAC() is deprecated and should be replaced with EVP_MAC API calls
      • ERR_func_error_string() is deprecated
      • OpenSSL has introduced a new concept of crypto providers (OSSL_PROVIDER), library context (OPENSSL_CTX) and additional flags. A new function EVP_MD_fetch() has been introduced.
      • FIPS support has been rewritten and is now shipped with OpenSSL 3.0.0. EVP_MD_CTX_FLAG_NON_FIPS_ALLOW is no longer supported. FIPS state is no longer part of EVP_MD_CTX but of EVP_MD.

      See https://wiki.openssl.org/index.php/OpenSSL_3.0

      Simple benchmark with openssl-3.0.0-5.el9.x86_64

      Something went wrong with Miss Islington.
      3ce6945 / #74758 is backport to 3.10.

      There is a missing call to va_end() in 443b308 (which is undefined behavior). PR 31153 fixes this.

      closing as the bulk of this appears done but it isn't clear what 100% is. If there are remaining deprecated APIs in use we can open individual issues for those and clean them up as needed going forwards.
