Add support for cipher aliases DHE, EDH and EECDH.
Add define SSL_CTRL_GET_CHAIN_CERTS to help hitch and other programs detect SSL_CTX_get0_chain_certs is supported.
Add wolfSSL_get_locking_callback.
Allow using ECDHE+RSA cipher suites when ECDHE alias is used while in OpenSSL compatibility mode.
Add more alerts for hitch.
SSL_CM should use the CTX's x509_store_pt if available.
Add support for SSL_CERT_FILE and SSL_CERT_DIR. Load default OpenSSL TLS 1.3 ciphers when using OPENSSL_COMPATIBLE_DEFAULTS.
Use wolfSSL_sk_X509_new_null to allocate WOLFSSL_STACK in wolfSSL_CTX_get_extra_chain_certs. Previous approach of malloc'ing without setting type/memsetting was leading to a segfault.
Add --enable-hitch.
hitch: Add unit tests for new APIs, fix a couple of issues uncovered by unit testing.
Correct behavior of wolfSSL_BIO_set_mem_buf for BIO_CLOSE/NOCLOSE and update unit test accordingly.
Add Github action test for hitch.
