* For SSL/TLS client and server connections, one of:
- * OpenSSL 1.0 or newer
- * LibreSSL
- * mbedTLS
- * GnuTLS
+ * OpenSSL 1.0.0 or newer (--enable-openssl)
+ * LibreSSL (--enable-openssl)
+ * mbedTLS (--enable-mbedtls)
+ * GnuTLS (--enable-gnutls)
- * For certificate-based oper CHALLENGE, OpenSSL 1.0 or newer.
+ * For certificate-based oper CHALLENGE, OpenSSL 1.0.0 or newer.
(Using CHALLENGE is not recommended for new deployments, so if you want to use a different TLS library,
feel free.)
- * For ECDHE, OpenSSL 1.0.0 or newer is required. Solaris; and RHEL/Fedora and its derivatives such as CentOS
- have removed support for ECC/ECDHE. You will need to compile your own OpenSSL on these systems.
+ * For ECDHE under OpenSSL, on Solaris and RHEL/Fedora (and its derivatives such as CentOS) you will
+ need to compile your own OpenSSL on these systems, as they have removed support for ECC/ECDHE.
+ Alternatively, consider using another library (see above).
