A value representing the version number as reported by the loaded version of OpenSSL.

Remarks

Before using SafeEvpPKeyHandle to perform interop with OpenSSL a caller must ensure that the version of OpenSSL they are calling is the same as the version the .NET runtime is calling, and not a side-by-side version.

For OpenSSL 1.1.0 and newer, this value is reported from the OpenSSL_version_num() function. When an older version of OpenSSL is in use, this value is reported from the SSLeay() function.

Callers are encouraged to only perform an equality check with this value.
