|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
Not all cipher implementations support keys as raw bytes. E.g. PKCS#11 tokens
|
||
|
|
can store them internally without any option to get the raw byte representation.
|
||
|
|
|
||
|
|
This tool is designed for managing opaque symmetric keys.
|
||
|

|
=over 4
|
||
|
|
|
||
|
|
=item B<-help>
|
||
|
|
|
||
|
|
Print out a usage message.
|
||
|
|
|
||
|
|
=item B<-cipher> I<cipher>
|
||
|
|
|
||
|
|
The cipher to generate the key for.
|
||
|
|
|
||
|
|
=item B<-skeymgmt> I<skeymgmt>
|
||
|
|
|
||
|
|
Some providers may support opaque symmetric keys objects. To use them, we need
|
||
|
|
to know the I<skeymgmt>. If not specified, the name of the cipher will be used.
|
||
|
|
|
||
|
|
To find out the name of the suitable symmetric key management,
|
||
|
|
please refer to the output of the C<openssl list -skey-managers> command.
|
||
|
|
|
||
|
|
=item B<-skeyopt> I<opt>:I<value>
|
||
|
|
|
||
|
|
To obtain an existing opaque symmetric key or to generate a new one, key
|
||
|
|
options are specified as opt:value. These options can't be used together with
|
||
|
|
any options implying raw key either directly or indirectly.
|
||
|
|
|
||
|
|
=item B<-genkey>
|
||
|
|
|
||
|
|
Generate a new opaque key object.
