Hello, experts!
A have a task to verify cms message with openssl command line, the operation
is:
*openssl smime -verify -in [fileName] -inform der -noverify -out
[outputFileName]*
(noverify argument is because i have a problem with root cert and now i need
to solve first problem - verify digital

utility for this by turning off all verification:
openssl smime -verify -in message -noverify -nosigs -signer s.pem
Then extract the final signature in binary form: in the asn1parse output look
for the final OCTET STRING and note its offset (number before

This isn't a proper DigestInfo structure at all it's just presumably the raw

Great, thanks a lot. I've been able to reproduce this on the erroneous

Hello,
I'm trying to verify an email signature using openssl.
I've saved the complete mail to a file named mail.eml, then I'm using
openssl to verify:
openssl smime -inform SMIME -CAfile all.pem -verify -in mail.eml
which gives an error:
2674688:error:0D0680A8:asn1 encoding

It sounds like the signature is malformed. That wouldn't cause problems with
asn1parse but would

However for some strange reason, openssl smime -verify keeps
reporting digest_failure. I have tried all of the following
commands:
openssl smime -verify -inform DER -in sig.tmp -binary -content data.tmp
-noverify -out /dev/null
openssl smime -verify -inform DER -in sig.tmp -content

Note that you normally MUST verify the validity of the sender's
certificate against a trusted root cert which you retrieved in a
secure way. Otherwise you have to make sure

The email is always checked against the senders certificate: it is
extracted from the signed email automatically so there is no need to

Hi
HELP
When I just use the root ca(vsign1.pem) and do not add my public trusted ca
in the file.
The program is saying verification successful.
What does it mean.
And how will I avoid the verification of root ca. I want it to stop after
verifying my public ca.

It means the signature on the message is valid (it has not been tampered

. Are
trying to set up things so only email signed with one certificate (as
opposed to anything chained to the trusted root CAs) is actually
verified? If so you can use something like:
openssl smime -verify -noverify -nointern -nochain -in message.txt
-certfile myfile.pem
Then only messages signed
Hi
Thanks a lot for your patience. All I want is the one you mentioned here.
openssl smime -verify -noverify -nointern -nochain -in message.txt
-certfile myfile.pem
And I am saved. and a VERY HAPPY NEW YEAR

Hi
Thanks a lot for your help. I converted the .p7c to .pem using this
openssl pkcs7 -in key.p7c -inform DER -print_certs
And I am trying to verify. I am getting Verification failure.
Why!!! . What should I do.
