OpenSSL 3.4 Introduces New APIs, FIPS Updates
linuxiac, Thursday, October 24th, 2024
OpenSSL 3.4 brings new cryptographic features, including integrity-only cipher suites for TLS 1.3, ECC optimizations, and FIPS provider updates.
OpenSSL has released version 3.4, which introduces some important modifications and is potentially incompatible with OpenSSL 3.3 in some cases.
Among the major changes, the 'TS_VERIFY_CTX_set_*' functions have been deprecated in favor of new 'TS_VERIFY_CTX_set0_*' replacements, which promise improved semantics.
Windows users will also see a redesign in how OPENSSLDIR, ENGINESDIR, and MODULESDIR directories are used-these locations can now be defined at runtime using registry keys, as opposed to the previous build-time configuration.
