.BI "\-+, \-\-options " file
Read command line options from \fIfile\fR.
.TP
.BI "\-i, \-\-in " file
Holder certificate to issue an attribute certificate for. If not given the
certificate is read from \fISTDIN\fR.
.TP
.BI "\-m, \-\-group " membership
Group membership the attribute certificate shall certify. The specified group
is included as a string. To include multiple groups, the option can be repeated.
.TP
.BI "\-k, \-\-issuerkey " file
Issuer private key file. Either this or
.B \-\-issuerkeyid
is required.

.B \-\-issuerkey
is required.
.TP
.BI "\-c, \-\-issuercert " file

.TP
.BI "\-l, \-\-lifetime " hours
Hours the attribute certificate is valid, default: 24. Ignored if both
an absolute start and end time are given.
.TP
.BI "\-F, \-\-not-before " datetime

defined by the
.B \-\-dateform
option.
.TP
.BI "\-T, \-\-not-after " datetime

determined based on the type and size of the signature key.
.TP
.BI "\-f, \-\-outform " encoding
Encoding of the created certificate file. Either \fIder\fR (ASN.1 DER) or

.SH "EXAMPLES"
.
To save repetitive typing, command line options can be stored in files.
Lets assume
.I acert.opt
contains the following contents:
.PP
.EX
  --issuercert aacert.der --issuerkey aakey.der --digest sha256 --lifetime 4
.EE
.PP
Then the following command can be used to issue an attribute certificate based
on a holder certificate and the options above:
.PP
.EX
  pki --acert --options acert.opt --in holder.der --group sales --group finance -f pem
.EE
.PP
