NSS Tools cmsutil

Using cmsutil

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

` <#syntax_2>`__ Syntax

To run cmsutil, type the command cmsutiloption[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 specify an action. Option arguments modify an action. The options and arguments for the cmsutil command are defined as follows:

Options
-D	Decode a message.
-C	Encrypt a message.
-E	Envelope a message.
-O	Create a certificates-only message.
-S	Sign a message.
Arguments
-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&nbsprecipient1,recipient2, . .&nbsp.	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 <tt>certUsageEmailSigner)</tt>.
<-Y ekprefnick	Specify an encryption key preference by nickname.
