Examples

Create policy list

Assuming there have been two element file mle.elt and pconf.elt generated by lcp_crtpolelt(8) The following example can create an unsigned policy list:

lcp_crtpollist --create --out list-unsig.lst mle.elt pconf.elt

Sign policy list

Unsigned policy list can be signed by the command lcp_crtpollist(8) or openssl(1). The openssl(1) signing is supported for cases where the signing environment is separate from  the policy creation environment and the software allowed to run there is  strictly controlled and already supports openssl(1).

The following example uses openssl(1) to sign the list:

1 openssl rsa -pubout -in privkey.pem -out pubkey.pem
2 cp list-unsig.lst list-sig.lst
3 lcp_crtpollist --sigh --pub pubkey.pem --nosig --out list-sig.lst
4 openssl genrsa -out privkey.pem 2048
5 openssl dgst -sha1 -sign privkey.pem -out list.sig list-sig.lst
6 lcp_crtpollist --addsig --sig list.sig --out list-sig.lst

lcp_crtpollist can also be used to sigh a policy list. The following example are intended to be mutually exclusive with the preceding example.

1 openssl genrsa -out privkey.pem 2048
2 openssl rsa -pubout -in privkey.pem -out pubkey.pem
3 cp list-unsig.lst list-sig.lst
4 lcp_crtpollist --sign --pub pubkey.pem --priv privkey.pem --out list-sig.lst
