Verification failure: CMS routines:cms_signerinfo_verify_cert:certificate verify error:..cms_smime.c:253:Verify error:self signed certificate

1: Created private key and certificate by using following command

openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:4096 -keyout private.key -out certificate.crt

2: Have simple text file to sign

$ cat message.txt
this is a test file.

3: Signed it with

 openssl cms -sign -in message.txt -text -out OutMessage.txt -inkey private.key -signer certificate.crt

4: for verification

openssl cms -verify -in OutMessage.txt -signer user.pem -out signedtext.txt

I am not sure why I am getting following error while verification step is performed, Please some one can help me out.

$ openssl cms -verify -in OutMessage.txt -signer  user.pem -out signedtext.txt

You're getting an error as you're using a self signed certificate, at least that's what the error is telling you. You can either add the certificate to your trust, or disable the certificate verify check when executing the command with the -no_signer_cert_verify option.
