CMSUTIL(1)                    NSS Security Tools                    CMSUTIL(1)



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.
