       cmsutil - Performs basic cryptograpic operations, such as encryption and decryption, on
       Cryptographic Message Syntax (CMS) messages.

       cmsutil [options] [[arguments]]

       This documentation is still work in progress. Please contribute to the initial review in
       Mozilla NSS bug 836477[1]

       The cmsutil command-line uses the S/MIME Toolkit to perform basic operations, such as
       encryption and decryption, on Cryptographic Message Syntax (CMS) messages.

       To run cmsutil, type the command cmsutil option [arguments] where option and arguments are
       combinations of the options and arguments listed in the following section. Each command
       takes one option. Each option may take zero or more arguments. To see a usage string,
       issue the command without options.


       Options specify an action. Option arguments modify an action. The options and arguments
       for the cmsutil command are defined as follows:

	   Decode a message.

	   Encrypt a message.

	   Envelope a message.

	   Create a certificates-only message.

	   Sign a message.


       Option arguments modify an action.

	   Decode a batch of files named in infile.

       -c content
	   Use this detached content (decode only).

       -d dbdir
	   Specify the key/certificate database directory (default is ".")

       -e envfile
	   Specify a file containing an enveloped message for a set of recipients to which you
	   would like to send an encrypted message. If this is the first encrypted message for
	   that set of recipients, a new enveloped message will be created that you can then use
	   for future messages (encrypt only).

       -f pwfile
	   Use password file to set password on all PKCS#11 tokens.

	   Include a signing time attribute (sign only).

       -H hash
	   Use specified hash algorithm (default:SHA1).

       -h num
	   Generate email headers with info about CMS message (decode only).

       -i infile
	   Use infile as a source of data (default is stdin).

	   Keep decoded encryption certs in permanent cert db.

       -N nickname
	   Specify nickname of certificate to sign with (sign only).

	   Suppress output of contents (decode only).

       -o outfile
	   Use outfile as a destination of data (default is stdout).

	   Include an S/MIME capabilities attribute.

       -p password
	   Use password as key database password.

       -r recipient1,recipient2, ...
	   Specify list of recipients (email addresses) for an encrypted or enveloped message.
	   For certificates-only message, list of certificates to send.

	   Suppress content in CMS message (sign only).

       -u certusage
	   Set type of cert usage (default is certUsageEmailSigner).

	   Print debugging information.

       -Y ekprefnick
	   Specify an encryption key preference by nickname.

       Encrypt Example

	   cmsutil -C [-i infile] [-o outfile] [-d dbdir] [-p password] -r "recipient1,recipient2, . . ." -e envfile

       Decode Example

	   cmsutil -D [-i infile] [-o outfile] [-d dbdir] [-p password] [-c content] [-n] [-h num]

       Envelope Example

	   cmsutil -E [-i infile] [-o outfile] [-d dbdir] [-p password] -r "recipient1,recipient2, ..."

       Certificate-only Example

	   cmsutil -O [-i infile] [-o outfile] [-d dbdir] [-p password] -r "cert1,cert2, . . ."

       Sign Message Example

	   cmsutil -S [-i infile] [-o outfile] [-d dbdir] [-p password] -N nickname[-TGP] [-Y ekprefnick]
