When an error occurs, use errx() instead of err() to display the error message, because openssl has its own error record. When an error occurs, errno will not be changed, while err() displays the errno error message. It will cause confusion. For example, when CMS_add1_signer() fails, the following message will appear: sign-file: CMS_add1_signer: Success errx() ignores errno and does not cause such issue.
