how to know a DN

hi all锛

      I am new to this list. I have some questions about using SFL.
I compiled the mimetest tool and successfully generated a signed
file (.eml) with the settings in the test enviroment. Then I added 
some entries in the config files, and managed to generate a new signed mail
using my own .pfx file. I am glad that outlook express can read this mail. 

	To use my .pfx file, I have to login with it and add a Login1=<DN> entry
in the config file (similiar to the one in test\hilevel\SignedData\SignedMIME.cfg).
My question is that how can I obtain the <DN> string of a certain .pfx file,
(in my example, I get it by debugging and tracing the program.) or do I have
other easier method to indicate which login to use.

Thank you very much.

sincerely
