=head1 NAME

	sign - OpenCA PKCS#7 Sign Tool

=head1 SYNOPSIS

	sign [-in file][-out file][-cert file][-keyfile file]
	[-key passwd][-nd][-verbose]

=head1 DESCRIPTION

You can find two programs in this distro: sign and verify. The first signs
given data, adds to the signature a time, the siger's certificate and, if
wanted, the data (not encrypted).

Signing tool syntax is as follows:

usage: sign args

 -in file        - Input file
 -out file       - File where to write to
 -cert file      - Certificate file
 -keyfile file   - Sign key file
 -key            - Password protecting the private key
 -nd             - No detach signature
 -verbose        - Verbose printing

Jus one note on the -nd flag: when used the data is added to the PKCS7
structure toghether with signature and other stuff. It is possible to
retrieve such data using the corresponding verify tool.

=head1 EXAMPLE

	sign -in README -out README.sig -cert cert.pem -keyfile key.pem \
		-key mypasswd -nd
