DESCRIPTION
|
|
|
|
NSS can store fixed keys as well as asymetric keys in the database. The
|
|
symkeyutil command can be used to manage these keys.
|
|
|
|
As with certutil, symkeyutil takes two types of arguments, commands and
|
|
options. Most commands fall into one of two catagories: commands which
|
|
create keys and commands which extract or destroy keys.
|
|
|
|
Exceptions to these catagories are listed first:
|
|
|
|
-H takes no additional options. It lists a more detailed help message.
|
|
-L takes the standard set of options. It lists all the keys in a the
|
|
specified token (NSS Internal DB Token is the default). Only the
|
|
-L option accepts the all option for tokens to list all the fixed
|
|
keys.
|
|
|
|
Key Creation commands:
|
|
For these commands, the key type (-t) option is always required.
|
|
In addition, the -s option may be required for certain key types.
|
|
The standard set of options may be specified.
|
|
|
|
-K Create a new key using the token key gen function.
|
|
-I Import a new key from the raw data specified in the data file,
|
|
specified with the -k options (required). This command may fail on
|
|
some tokens that don't support direct import of key material.
|
|
-U Unwrap a new key from an encrypted data file specified with the -k
|
|
option. The -w, -x, or -y option specifies the unwrapping key.
|
|
The unwrapping algorithm is selected based on the type of the
|
|
unwrapping key.
|
|
|
|
Key extraction/destruction options:
|
|
For these keys, one and only of of the -n, -i, or -j options must be
|
|
specified. If more than one key matches the -n option, the 'first' key
|
|
matching will be used. The standard set of options may be specified.
|
|
|
|
-D Delete the key specified by the -n, -i, or -j options.
|
|
-E Export the key specified by the -n, -i, or -j options and store the
|
|
contents to a file specified by the -k file (required).
|
|
This command will seldom work on any token since most keys are
|
|
protected from export.
|
|
-W Wrap the key specified by the -n, -i, or -j options and store the
|
|
encrypted contents to a file specified by the -k file (required).
|
|
The -w, -x, or -y option specifies the key used to wrap the
|
|
target key.
|
|
-M Move the key specified by the -n, -i, or -j options to the token
|
|
specified by the -g option (required). The new key will have the
|
|
same attributes as the source key.
|
|
|
|
OPTIONS
|
|
|
|
Standard options are those options that may be used by any command, and
|
|
whose meaning is the same for all commands.
|
|
|
|
-h token Specify the token which the command will operate on.
|
|
If -h is not specified the internal token is presumed. In
|
|
addition the special value 'all' may be used to specify
|
|
that all tokens should be used. This is only valid for
|
|
the '-L' command.
|
|
-d certdir Specify the location of the NSS databases. The default
|
|
value is platform dependent.
|
|
-P dbprefix Specify the prefix for the NSS database. The default value
|
|
is NULL.
|
|
-p password Specify the password for the token. On the command line.
|
|
The -p and -f options are mutually exclusive. If
|
|
neither option is specified, the password would be
|
|
prompted from the user.
|
|
-f passwordFile Specify a file that contains the password for the token.
|
|
This option is mutually exclusive to the -p option.
|
|
|
|
In addition to the standard options are the following command specific
|
|
options are.
|
|
|
|
-r Opens the NSS databases Read/Write. By default the -L,
|
|
-E, and -W commands open the database read only. Other
|
|
commands automatically opens the databases Read/Write and
|
|
igore this option if it is specified.
|
|
|
|
-n name Specifies the nickname for the key.
|
|
|
|
For the -K, -I, or -U options, name is the name for
|
|
the new key. If -n is not specified, no name is
|
|
assumed. There is not check for duplicate names.
|
|
|
|
For the -D, -E, -W, or -M, the name specifies the key to
|
|
operate on. In this case one andy only one of the -n, -i
|
|
or -j options should be specifed. It is possible that
|
|
the -n options specifies and ambiguous key. In that case
|
|
the 'first' valid key is used.
|
|
|
|
For the -M option, the nickname for the new key is copied
|
|
from it's original key, even if the original key is
|
|
specified using -i or -j.
|
|
|
|
-i key id
|
|
-j key id file These options are equivalent and mutually exclusive.
|
|
They specify the key id for the file. The -i option
|
|
specifies the key id on the command line using a hex
|
|
string. The -j specifies a file to read the raw key
|
|
id from.
|
|
|
|
For the -K, -I, or -U options, key id is the key id for
|
|
the new key. If -i or -j is not specified, no key id
|
|
is assumed. Some tokens may generate their own unique
|
|
id for the key in this case (but it is not guarrenteed).
|
|
|
|
For the -D, -E, -W, or -M, the key id specifies the key to
|
|
operate on. In this case one andy only one of the -n, -i
|
|
or -j options should be specifed.
|
|
|
|
-t type Specifies the key Type for the new key. This option is
|
|
required for the -K, -I, and -U commands. Valid values
|
|
are:
|
|
generic, rc2, rc4, des, des2, des3, cast, cast3,
|
|
cast5, cast128, rc5, idea, skipjack, baton, juniper,
|
|
cdmf, aes, camellia
|
|
|
|
Not all tokens support all key types. The generic key
|
|
type is usually used in MACing and key derivation
|
|
algorithms. Neither generic nor rc4 keys may be used
|
|
to wrap other keys. Fixed rc4 keys are dangerous since
|
|
multiple use of the same stream cipher key to encrypted
|
|
different data can compromise all data encrypted with
|
|
that key.
|
|
|
|
-s size Specifies the key size. For most situations the key size
|
|
is already known and need not be specified. For some
|
|
algorithms, however, it is necessary to specify the key
|
|
size when generation or unwrapping the key.
|
|
|
|
-k key file Specifies the name of a file that contains key data to
|
|
import or unwrap (-I or -U), or the location to store
|
|
key data or encrypted key data (-E or -W).
|
|
|
|
-g target token Specifies the target token when moving a key (-M). This
|
|
option is required for the -M command. It is invalid for
|
|
all other commands.
|
|
|
|
|
|
|
|
-w wrap name
|
|
-x wrap key id
|
|
-y wrap key id file Specifies the wrapping key used int the -U and -W
|
|
command. Exactly one of these must be specified for the
|
|
-U or -W commands. Same semantics as the -n, -i, and -j
|
|
options above.
|
|
|
|
BUGS
|
|
|
|
There is no way display the key id of a key.
|
|
|
|
The -p and -f options only specifies one password. Multiple passwords may
|
|
be needed for the -L -h all command and the -M command.
|
|
|
|
Perhaps RC4 should not be supported as a key type. Use of these keys as
|
|
fixed keys is exceedingly dangerous.
|
|
|
|
The handling of multiple keys with the same nickname should be more
|
|
deterministic than 'the first one'
|
|
|
|
There is no way to specify, or display the operation flags of a key. The
|
|
operation flags are not copied with the -M option as they should be.
|
|
|
|
There is no way to change the attributes of a key (nickname, id, operation
|
|
flags).
