- New stable release incorporating all changes from developer releases 1.91_01
to 1.91_03.
- Summary of major changes since version 1.90:
- Net::SSLeay now supports stable releases of OpenSSL 3.0.
- OpenSSL 3.0.0 introduces the concept of "providers", which contain
cryptographic algorithm implementations. Many outdated, deprecated and/or
insecure algorithms have been moved to the "legacy" provider, which may
need to be loaded explicitly in order to use them with Net::SSLeay. See
"Low level API: OSSL_LIB_CTX and OSSL_PROVIDER related functions" in the
Net::SSLeay module documentation for details.
- Net::SSLeay's built-in PEM_get_string_PrivateKey() function depends on
algorithms that have moved to the legacy provider described above; if
OpenSSL has been compiled without the legacy provider, the tests
t/local/33_x509_create_cert.t and t/local/63_ec_key_generate_key.t will
fail when the test suite is run.
- TLS 1.1 and below may only be used at security level 0 as of OpenSSL
3.0.0; if a minimum required security level is imposed (e.g. in an
OpenSSL configuration file managed by the operating system), the tests
t/local/44_sess.t and t/local/45_exporter.t will fail when the test suite
is run.
- Net::SSLeay now supports stable releases of LibreSSL from the 3.2 - 3.4
series (with the exception of 3.2.2 and 3.2.3 - see "COMPATIBILITY" in the
Net::SSLeay module documentation for details).
- The TLS 1.3 implementation in LibreSSL 3.1 - 3.3, parts of which are
enabled by default, is not fully compatible with the libssl API and may
not function as expected with Net::SSLeay; see "KNOWN BUGS AND CAVEATS"
in the Net::SSLeay module documentation for details.
- A number of new libcrypto/libssl constants and functions are now exposed,
including SSL_CTX_set_keylog_callback() and SSL_CTX_set_msg_callback(),
which are helpful when debugging TLS handshakes. See the release notes for
the 1.91 developer releases below for a full list of newly-exposed
constants and functions.
