NAME
       cmsutil - Performs basic cryptograpic operations, such as encryption
       and decryption, on Cryptographic Message Syntax (CMS) messages.
SYNOPSIS
       cmsutil [options] [[arguments]]
STATUS
       This documentation is still work in progress. Please contribute to the
       initial review in Mozilla NSS bug 836477[1]
DESCRIPTION
       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 AND ARGUMENTS
       Options
       Options specify an action. Option arguments modify an action. The
       options and arguments for the cmsutil command are defined as follows:
       -C
           Encrypt a message.
       -D
           Decode a message.
       -E
           Envelope a message.
       -O
           Create a certificates-only message.
       -S
           Sign a message.
       Arguments
       Option arguments modify an action.
       -b
           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.
       -G
           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).
       -k
           Keep decoded encryption certs in permanent cert db.
       -N nickname
           Specify nickname of certificate to sign with (sign only).
       -n
           Suppress output of contents (decode only).
       -o outfile
           Use outfile as a destination of data (default is stdout).
       -P
           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.
       -T
           Suppress content in CMS message (sign only).
       -u certusage
           Set type of cert usage (default is certUsageEmailSigner).
       -v
           Print debugging information.
       -Y ekprefnick
           Specify an encryption key preference by nickname.
