[openssl-users] Error signing document

[m.de.groot]

Dear Openssl,

I have the following case:
I am trying to sign a file with a private key from an CA. 
I converted the pfx file to a pem file using the following command
openssl pkcs12 -in CustKeyIcBD001.pfx -out CustKeyIcBD001.pem -nodes

After this I trying to sign a file using this key with the following command

openssl cms -sign -in TestfileIN.txt -out TestfileSign.tmp -outform DER -binary -nodetach -md SHA1 –signer CustKeyIcBD001.pem

However I keep getting the message

No signer certificate specified

I have put all files in the same directory and don't see why this is going wrong.

Can anybody help me out on this?

Regards,
Mark
