| decryption, on Cryptographic Message Syntax (CMS) messages.
Synopsis
cmsutil [options] `arguments <arguments>`__
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

| and arguments for the cmsutil command are defined as follows:
-D
Decode a message.
-C
Encrypt a message.
-E
Envelope a message.
-O
Create a certificates-only message.
-S
Sign a message.
Arguments
Option arguments modify an action and are lowercase.
-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).
-G
Include a signing time attribute (sign only).
-h num
Generate email headers with info about CMS message (decode only).
-i infile
Use infile as a source of data (default is stdin).
-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).
-Y ekprefnick
Specify an encryption key preference by nickname.
Usage
Encrypt Example
cmsutil -C [-i infile] [-o outfile] [-d dbdir] [-p password] -r "recipient1,recipient2, . . ." -e
