OpenSSL 3.4 Alpha 1 Released With New Features

The first alpha release of OpenSSL 3.4 is now available for testing as the next feature update to this widely-used SSL library / cryptography toolkit.

With OpenSSL 3.4 there are a number of features baking compared to OpenSSL 3.3 and prior. Some of the new features as of OpenSSL 3.4 Alpha 1 include:

- Added FIPS indicators to the FIPS provider as part of FIPS 140-3 requirements.

- A new random seed source RNG JITTER using a statically-linked jitterentropy library.

- The "openssl list" command can now retrieve configured TLS signature algorithms.

- Improved Base64 BIO correctness and error reporting.

- Support for HMAC hardware acceleration on the IBM s390x architecture.

- RFC 9579 (PBMAC1) implementation in PKCS#12

- Support for directly-fetched composite signature algorithms like RSA-SHA2-256.

- Support for RFC 9150 with integrity-only cipher suites TLS_SHA256_SHA256 and TLS_SHA384_SHA384 in TLS 1.3

- Attribute Certificate (RFC 5755) support.

- OpenSSL now supports building Position Independent Executables (PIE) with a new "enable-pie" configuration option to support Address Space Layout Randomization (ASL)R with the OpenSSL executable.
