Question  - extracting root pass

Hi,

Haven't found the issue page, and have spent the last 6 hours trying to figure out the issue...

When trying to extract root pass as described in readme, I get the following:

Error reading S/MIME message
140554352330400:error:0D0D40D1:asn1 encoding routines:SMIME_read_ASN1:no content type:asn_mime.c:451:


Please advise, would really appreciate it.
