Changes for version 1.94 - 2024-01-08

  • New stable release incorporating all changes from developer releases 1.93_01 to 1.93_05.
  • Summary of major changes since version 1.92:
    • Net::SSLeay now officially supports all stable releases of OpenSSL 3.1 and 3.2, and LibreSSL 3.5 - 3.8.
    • Many noisy compiler warnings have been silenced - if SSLeay.xs fails to compile, it should now be much easier to identify the cause.
    • libcrypto's OPENSSL_init_crypto() function and libssl's OPENSSL_init_ssl() function are now exposed, enabling fine-grained control over the initialisation and configuration of both libraries.
    • libssl functions implementing TLS 1.3 PSK authentication are now exposed, in particular SSL_CTX_set_psk_find_session_callback() (on the server side) and SSL_CTX_set_psk_use_session_callback() (on the client side).
    • libssl functions implementing server-side TLS 1.2 PSK authentication are now exposed, in particular SSL_CTX_set_psk_server_callback().
    • libssl's SSL_CTX_set_client_hello_cb() function is now exposed, allowing a TLS server to set a callback function that is executed when the server processes a ClientHello message.
    • Many more libcrypto/libssl constants and functions are now exposed; see the release notes for the 1.93 developer releases for a full list.

Changes for version 1.93_05 - 2024-01-06

  • Remove support for automatic detection of libssl/libcrypto via pkg-config with ExtUtils::PkgConfig if it is installed, due to the compiler and linker options provided by pkg-config being used unconditionally (which is incompatible with the OPENSSL_PREFIX detection method). The implementation of this was merged in time for developer release 1.93_03 and therefore hasn't been included in a stable release yet, so this doesn't represent a breaking change to the way in which libssl/libcrypto are detected by Makefile.PL. This is, however, a very useful feature, and we intend to bring it back in time for Net-SSLeay 1.96 after ironing out the remaining bugs.

Changes for version 1.93_04 - 2024-01-05

  • Use -DOPENSSL_API_COMPAT=908 when compiling SSLeay.xs to suppress OpenSSL deprecation warnings.
  • Expose a number of functions that were added in recent LibreSSL releases or were not otherwise exposed before:
    • SSL(_CTX)_get/set_security_level in LibreSSL 3.6.0
    • SSL(_CTX)_get/set_num_tickets in LibreSSL 3.5.0
    • SSL(_CTX)_set_ciphersuites in LibreSSL 3.4.0
    • EVP_PKEY_security_bits in LibreSSL 3.6.0
    • SSL_CTX_set_keylog_callback in LibreSSL 3.5.0
    • SSL_is_dtls in LibreSSL 3.3.2
  • Remove Tuure Vartiainen as an active contributor. Tuure's contributions were instrumental in the transition from ad hoc testing to CI-based testing, which has greatly improved Net-SSLeay's stability, reliability and compatibility. Thanks for your contributions, Tuure!

Changes for version 1.93_03 - 2024-01-02

  • Pass RAND_seed()'s sole argument to the underlying RAND_seed() function in libcrypto, rather than passing the value of a non-existent second argument. Fixes GH-427. Thanks to cgf1 for the report.
  • Avoid explicit and implicit use of weak hash algorithms, such as MD5 and SHA-1, in test suite. This allows tests 44_sess.t and 45_exporter.t to correctly work on systems where crypto policies prohibit their direct use and TLS versions that require them. An example of such a system is Rocky Linux 9.2. Any Red Hat Enterprise Linux 9 and derived system is likely to have similar behaviour. Thanks to Paul Howarth for the investigation and patches.
  • LibreSSL 3.8.0 release notes state: The POLICY_TREE and its related structures and API were removed. The affected Net::SSLeay functions are:
    • X509_policy_level_get0_node
    • X509_policy_level_node_count
    • X509_policy_node_get0_parent

    • X509_policy_tree_get0_level
    • X509_policy_tree_get0_policies
    • X509_policy_tree_get0_user_policies
    • X509_policy_tree_level_count Patch by GitHub user orbea.
  • Add OpenSSL 3.1 and LibreSSL 3.7 minor releases to GitHub CI testing. Update the previous minor releases to their latest versions. Add NetBSD to BSDs job and update the other BSDs and Alpine Linux jobs to cover additional and latest releases. Use the latest MacOS runners.
  • Expose SSL_CTX_set_client_hello_cb for setting a callback the server calls when it processes a ClientHello. Expose the following functions that can be called only from the callback. None of these are available with LibreSSL.
    • SSL_client_hello_isv2

  • Expose NID_shake128, NID_shake256 and the rest of NID_sha* constants.
  • Expose functions for setting up TLS 1.3 PSK authentication on the client side. Only SSL_SESSION_get0_cipher is available with LibreSSL.
    • SSL_set_psk_use_session_callback
    • SSL_CTX_set_psk_use_session_callback
    • SSL_CIPHER_get_handshake_digest
    • SSL_SESSION_get0_cipher
    • EVP_MD_get0_description
    • EVP_MD_get0_name
    • EVP_MD_get_type
  • Major documentation cleanup. Thanks to John Jetmore.
  • Add constants for specifying version field for certificates, certificate requests and CRLs. Available in OpenSSL 3.0:
    • X509_VERSION_1, X509_VERSION_2 and X509_VERSION_3
    • X509_REQ_VERSION_1, X509_REQ_VERSION_2 and X509_REQ_VERSION_3
    • X509_CRL_VERSION_1 and X509_CRL_VERSION_2
  • Remove conditional compilation checks from SSLeay.xs and compatilibty notes from SSLeay.pod for OpenSSL versions earlier than 0.9.8. This includes all 0.9.7 and earlier releases down to 0.9.3a. Update tests respectively.
  • Add OpenSSL 3.2 and LibreSSL 3.8 minor releases to GitHub CI testing. Update existing OpenSSL releases to 1.1.1w, 3.0.12 and 3.1.4.
  • Support compiling SSLeay.xs with a C++ compiler. Thanks to James E Keenan and GitHub user twata1 for suggesting this, testing and providing detailed test reports. Tested with GCC 13 g++, Clang 17 clang++ and Visual Studio Community 2022 C++ compilers. Discussion in GH-425 and GH-438.

    • OPENSSL_INIT_NO_LOAD_CONFIG
    • OPENSSL_INIT_NO_LOAD_CRYPTO_STRINGS
    • OPENSSL_INIT_NO_LOAD_SSL_STRINGS
  • Expose functions for OpenSSL libcrypto and libssl initialisation, configuration and deinitialisation. These are available in OpenSSL 1.1.0 and later:
    • OPENSSL_init_ssl and OPENSSL_init_crypto
    • OPENSSL_cleanup, also in LibreSSL 3.6.0
    • OPENSSL_INIT_new and OPENSSL_INIT_free
    • OPENSSL_INIT_set_config_filename

    • OPENSSL_INIT_set_config_file_flags
  • Add new test file 23_openssl_init.t for OPENSSL_init_ssl and related functions.
  • Support finding OpenSSL libraries using ExtUtils::PkgConfig. Thanks to Paul Howarth for the patch.
  • Fix a number of cases where variables were declared after code triggering Gcc and Clang warning -Wdeclaration-after-statement. This is supported by C language version C99 and used by Perl 5.35.5 and later. SSLeay.xs is likely compiled with compilers that do not support this, therefore such constructs are avoided in SSLeay.xs. Thanks to GitHub user bulk88 for the patch.
  • Fix _CRT_SECURE_NO_DEPRECATE warning on Windows. Fix OpenSSL library file path detection loop in Makefile.PL. Both thanks to bulk88.
  • Update Shining Light OpenSSL detection to work with OpenSSL 1.1.1w, 3.0.12, 3.1.4 and 3.2.0 installers. Caveats: when both 32bit and 64bit versions are installed, OpenSSL library path detection may pick the wrong version. Static compilation needs seems not to work with the these versions. Thanks to bulk88 for the initial updates.
  • Tone down Makefile.PL and README warning against mixing compilers and flags when compiling OpenSSL, Perl and Net::SSLeay. This may still be a requirement on some platforms, but, for example, with Linux and macOS mixing clang and gcc appears to work.
  • Add general installation instructions in README. Thanks to GitHub user viviparous. Update README and README.OSX.

Changes for version 1.93_02 - 2023-02-22

  • Update ppport.h to version 3.68. This eliminates thousands of compound-token-split-by-macro compiler warnings when building Net-SSLeay with Clang 12 or greater. Partially fixes GH-383.
  • Silence compound-token-split-by-macro warnings when building Net-SSLeay with Clang 12 or greater. Fixes the remainder of GH-383.
  • When building Net-SSLeay, search for the openssl binary in the same directory in which Perl is installed (i.e. $Config{prefix}/bin/). Thanks to Henrik Grimler for the patch.
  • Expose EVP_PKEY_security_bits. Thanks to Felipe Gasper.
  • Major update to Gihub Actions configuration. Thanks to Felipe Gasper. New testing targets are:
    • OpenSSL and LibreSSL on Alpine Linux on i386, x390x, arm32v6, ar32v7 and arm64v8 architectures.
    • OpenSSL and LibreSSL on Ubuntu on i386, x390x, ar32v7 and arm64v8 architectures.
    • OpenSSL on FreeBSD 13.0, not enabled yet because of GH #272 and #394
    • LibreSSL on FreeBSD 13.0
    • LibreSSL on OpenBSD 6.9
    • LibreSSL on OpenBSD 7.1
    • Cygwin on x86_64
  • Fix compilation failure using cl. Microsoft cl compiler do not like when preprocessor directives are inside a macro. Fixes GH-403. Thanks to Jean-Damien Durand.
  • Update CTX_use_PKCS12_file() and CTX_use_PKCS12_file() to use BIO functions for avoiding "no OPENSSL_Applink" runtime errors. Fixes GH-281 and RT#101638. Thanks to Jean-Damien Durand.
  • Add to README.Win32 more information about OPENSSL_Applink and how it may be needed with FILE pointers and POSIX/Unix fds. Recommended method is to avoid them and use OpenSSL BIO functions instead. Update SSLeay.pod with alternatives to Net::SSLeay::SESSION_print_fp(). Closes GH-411.
  • Refactor variable declarations in RSA_generate_key to allow SSLeay.xs to compile under -Werror=declaration-after-statement. Fixes GH-407. Thanks to dharanlinux for the report.
  • Fix memory leaks after calls to X509_get_ext_d2i. Thanks to Anton Borowka.
  • Documentation fix: Correct CRL revocation reasons in P_X509_CRL_add_revoked_serial_hex(). Closes GH-397. Reported by Marc Reisner.
  • Support stable releases of LibreSSL 3.5 and 3.6.
  • Update callback set by SSL_set_session_secret_cb to adjust master secret's length. This is needed with OpenSSL 1.1.1 and later that provide buffer that is now longer than 48 octets. Fix Net::SSLeay::get_keyblock_size() size calculation with AEAD ciphers. These functions were originally added to OpenSSL and Net::SSLeay for EAP-FAST. These changes allow EAP-FAST to work with AEAD ciphers and with OpenSSL versions 1.1.1 and later.
  • Remove code guarded by obsolete SSL_F_SSL_SET_HELLO_EXTENSION #ifdef. This was used by the initial EAP-FAST related OpenSSL patch which was never part of the OpenSSL distribution.
  • PEM_get_string_PrivateKey() currently uses DES-CBC as its default encryption algorithm. Test 33_x509_create_cert.t now skips testing the default algorithm on systems that support providers but don't have the legacy provider available. One such system is FreeBSD 13.0 with OpenSSL which was added as disabled in GitHub actions by PR GH-402 but can now be enabled. Long term fix is to replace DES-CBC with a modern cipher. Allows closing GH-394.

Changes for version 1.93_01 - 2022-03-20

  • LibreSSL 3.5.0 has removed access to internal data structures: Use X509_get0_tbs_sigalg() and OCSP_SINGLERESP_get0_id() like in OpenSSL 1.1. Also use RSA_get0... with RSA_get_key_parameters(). Thanks to Alexander Bluhm.
  • Expose SSL_CTX_get_min_proto_version(), SSL_CTX_get_max_proto_version(), SSL_get_min_proto_version() and SSL_get_max_proto_version() with LibresSSL 3.4.0 and later. Thanks to Alexander Bluhm.
  • Update tests 07_sslecho.t and 44_sess.t to work around failures seen on Windows with Perls earlier than 5.20. For the details, see GH-356 and look for CloseHandle() in Perl 5.20.0 changelog. Thanks to GitHub user twata1 for the report and additional help.
  • Alexander's recent work with RSA_get_key_parameters(), allows to make it available with all OpenSSL versions. It was already available with versions earlier than 1.1.0.
  • Expose BN_dup(), BN_clear(), BN_clear_free() and BN_free().
  • Use PTR2IV instead of direct cast to IV to fix compilation warning with SSLeay.xs internal function bn2sv().
  • Expose X509_CRL_get0_lastUpdate(), X509_CRL_get0_nextUpdate(), X509_CRL_set1_lastUpdate() and X509_CRL_set1_nextUpdate() that became available with OpenSSL 1.1.0 and LibreSSL 2.7.0. These, and the respective deprecated _get/set_ aliases, are available with all OpenSSL and LibreSSL versions. Fixes part of RT#124371.
  • Note in documentation that the X509_CRL_get* functions return a pointer to time structure that should be considered read-only.
  • Use ASN1_STRING_get0_data() instead of ASN1_STRING_data() to avoid compile time deprecation warnings. Partly fixes RT#124371.
  • Add the following constants from Current OpenSSL master branch:
    • SSL_ASYNC_PAUSED
    • SSL_ASYNC_NO_JOBS
    • SSL_CLIENT_HELLO_CB
    • SSL_ERROR_WANT_ASYNC
    • SSL_ERROR_WANT_ASYNC_JOB
    • SSL_ERROR_WANT_CLIENT_HELLO_CB
    • SSL_ERROR_WANT_RETRY_VERIFY
    • SSL_MODE_ASYNC
    • SSL_MODE_NO_AUTO_CHAIN
    • SSL_OP_ALLOW_CLIENT_RENEGOTIATION
    • SSL_OP_CLEANSE_PLAINTEXT
    • SSL_OP_DISABLE_TLSEXT_CA_NAMES
    • SSL_OP_ENABLE_KTLS
    • SSL_OP_IGNORE_UNEXPECTED_EOF
    • SSL_OP_NO_EXTENDED_MASTER_SECRET
    • SSL_RETRY_VERIFY
    • SSL_SESS_CACHE_UPDATE_TIME
    • X509_TRUST_DEFAULT
    • X509_V_ERR_AUTHORITY_KEY_IDENTIFIER_CRITICAL
    • X509_V_ERR_CA_BCONS_NOT_CRITICAL
    • X509_V_ERR_CA_CERT_MISSING_KEY_USAGE
    • X509_V_ERR_EC_KEY_EXPLICIT_PARAMS
    • X509_V_ERR_EMPTY_SUBJECT_ALT_NAME
    • X509_V_ERR_EMPTY_SUBJECT_SAN_NOT_CRITICAL
    • X509_V_ERR_EXTENSIONS_REQUIRE_VERSION_3
    • X509_V_ERR_ISSUER_NAME_EMPTY
    • X509_V_ERR_KU_KEY_CERT_SIGN_INVALID_FOR_NON_CA
    • X509_V_ERR_MISSING_AUTHORITY_KEY_IDENTIFIER
    • X509_V_ERR_MISSING_SUBJECT_KEY_IDENTIFIER
    • X509_V_ERR_NO_ISSUER_PUBLIC_KEY
    • X509_V_ERR_PATHLEN_INVALID_FOR_NON_CA
    • X509_V_ERR_PATHLEN_WITHOUT_KU_KEY_CERT_SIGN
    • X509_V_ERR_SIGNATURE_ALGORITHM_INCONSISTENCY
    • X509_V_ERR_SIGNATURE_ALGORITHM_MISMATCH
    • X509_V_ERR_SUBJECT_KEY_IDENTIFIER_CRITICAL
    • X509_V_ERR_SUBJECT_NAME_EMPTY
    • X509_V_ERR_UNSUPPORTED_SIGNATURE_ALGORITHM
  • Expose X509_get0_notBefore(), X509_getm_notBefore() X509_get0_nextAfter() and X509_getm_nextAfter() that became available with OpenSSL 1.1.0 and LibreSSL 2.7.0. These, and the deprecated _get functions, are available, as aliases when needed, with all OpenSSL and LibreSSL versions. Fixes GH-367.
  • Only export the TLSv1*_method() functions when support for the respective TLS version is available in the underlying libssl library. This allows Net::SSLeay to be built against libssl libraries that were compiled without support for old TLS versions.
