5.3 SSL Library-Dependent Capabilities

MySQL can be compiled using OpenSSL or wolfSSL, both of which enable encrypted connections based on the OpenSSL API:

  • MySQL Enterprise Edition binary distributions are compiled using OpenSSL. It is not possible to use wolfSSL with MySQL Enterprise Edition.

  • MySQL Community Edition binary distributions are compiled using OpenSSL.

  • MySQL Community Edition source distributions can be compiled using either OpenSSL or wolfSSL (see Section 5.4, “Building MySQL with Support for Encrypted Connections”).

OpenSSL and wolfSSL offer the same basic functionality, but MySQL distributions compiled using OpenSSL have additional features:

Certain OpenSSL-related system and status variables are present only if MySQL was compiled using OpenSSL:

To determine whether a server was compiled using OpenSSL, test the existence of any of those variables. For example, this statement returns a row if OpenSSL was used and an empty result if wolfSSL was used:

SHOW STATUS LIKE 'Rsa_public_key';
