class	Botan::TPM2::Session

Detailed Description

This wraps a Session object and ensures that the session's attributes are restored to their original state after they have been modified by a (failing) TSS2 library function.

This is a workaround for the fact that TSS2 library calls may modify the session's attributes and not reset them when the call fails.
