Issue/Introduction

What does the "Export failed, exception. "module" object has no attribute " PROTOCOL_SSLv2"" error mean?

Resolution

The "Export failed, exception. "module" object has no attribute " PROTOCOL_SSLv2"" error points to an unsupported session action which utilized the unsupported SSL 2.0 version. The "Module" could be a software module or HSM, depending on session.

Note:

This version of SSL Visibility supports SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, and has full support for the TLS 1.3 standard (RFC 8446), including support for earlier versions (draft 18 to draft 28).

There is no support for SSL 2.0. Should SSL 2.0 traffic be encountered, the SSL Visibility appliance will either Cut Through, Drop, or Reject the flow according to the Unsupported Session Actions setting in the segment configuration. SSL 2.0 Client Hello messages are supported, as long as the rest of the SSL handshake is done using version 3.0 or above (more detail on this compatibility mode can be found in Section E.1 of RFC4346).
