you can create text files on the local computer and transfer them
to the AM module using scp or a similar secure transfer
program.)
6. Change into the CD1.1 transmitter's configuration directory
using
cd /etc/libcd11
The following steps create a key pair and certificate request
within the token, which need to be placed in this directory for
the CD1.1 transmitter to be able to sign outgoing data.
7. Issue the command
spyrus newreq -s filename -i 1 -r slot01.req -p slot01.pub
-x
where filename is the name of the file you created in step 5.
This will generate a certificate request in the file slot01.req
and a public key in the file slot01.pub. The private key is
kept within the token itself, and cannot be extracted from it.
Any attempt to compromise the token will cause it to shut down
and become unusable.
8. The file slot01.req is a certificate request for the key pair
generated. You should send this file by e-mail to the
Certification Authority, so that they can generate a valid
certificate from it.
9. When you receive the certificate, install it in the
/etc/libcd11 directory as slot01.crt. Also create the key
ID file slot01.kid. (The key ID file is simply a text file
containing the key ID as a single decimal number. You can use
any key ID number as long as it is unique for each key. It is used
in the key bucket file, described below.)
10.Now load the certificate into the token using the command
spyrus loadcert -c slot01.crt
The token will check that the certificate matches its own key
pair, and should respond with
info::No index specified searching for matching key
info::Key in slot 1 matches certificate
