[openssl-users] Payload-checksum in PEM?

Hi!

I have a verification-error in a SMIME-message and I try to check 
manually the checksums of the payload.

Here is my strategy - but I do not know it is even possible.


# openssl cms -sign -in myfile.txt -md md5 -signer cer.txt -inkey 
key.txt -outform PEM > pem.txt

# md5sum myfile.txt

Can I expect to find the md5sum checksum somewhere in the ASN1 of pem.txt???

# openssl asn1parse -in pem.txt

As far I see it is not there - but maybe it is just a quick step to it?

Thanks for help!
Chris
