SRP client after successful second phase of handshake places adds wire crypt key to the list of known keys. That happens even in a case when SRP server later rejects authentication due to invalid password. If next plugin later adds wire crypt key of same type client has no way to distinguish between 2 keys and select first one.

Currently that's fixed by using correct direction (down, not up) of keys' scanning at client side.
