[stunnel-users] Problems with Stunnel 4.5*

[Sebastian Rose-Indorf]

Hello Mike, 
 
I can make only a statement about the Non-FIPS mode, because Stunnel 4.5*
starts only if "fips = no" is set (without Windows gives an error message).
 
I have tested both a RSA-SHA384/AES128 certificate/priv-key pair and a
RSA-RMD160/IDEA certificate/priv-key pair. Both does not work.
(SHA384/AES128 is validated by FIPS 140-2, but not provided by PKCS12. Could
it be due to it?)
 
Yours sincerely
Sebastian
