Hi,
I would like to use OpenSSL 0.97c for Windows to decrypt S/MIME encrypted
messages which contain attachments. I am especially interested in
decrypting the attachments.
The encrypted mail is available in a source file called
"source.msg" (see [1]).
I used the following command on this file:
openssl smime -decrypt -in c:\source.msg -recip c:\abr2006.pem.cer
-inkey c:\abr2006.pem -out c:\dest.msg
I had expected that the new file dest.msg would contain the decrypted
message. But as you can see in [2], the new file is still encrypted.
So what did I do wrong?
Are there any special steps I have to take to decrypt attachments?
Please don't mind if this is a dumb question, but I am new to OpenSSL
and I have no clue :-/
Thanks in advance for your answers!
With kind regards,
Christian
