DESCRIPTION

       This sub-command of pki(1) is used to issue an attribute certificate using an issuer certificate with its
       private key and the holder certificate.

OPTIONS

       -h, --help
              Print usage information with a summary of the available options.

       -v, --debug level
              Set debug level, default: 1.

       -+, --options file
              Read command line options from file.

       -i, --in file
              Holder  certificate  to  issue  an attribute certificate for. If not given the certificate is read
              from STDIN.

       -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.

       -k, --issuerkey file
              Issuer private key file. Either this or --issuerkeyid is required.

       -x, --issuerkeyid hex
              Key ID of a issuer private key on a smartcard. Either this or --issuerkey is required.

       -c, --issuercert file
              Issuer certificate file. Required.

       -l, --lifetime hours
              Hours  the  attribute certificate is valid, default: 24. Ignored if both an absolute start and end
              time are given.

       -F, --not-before datetime
              Absolute time when the validity of the AC begins. The datetime format is defined by the --dateform
              option.

       -T, --not-after datetime
              Absolute time when the validity of the AC ends. The datetime format is defined by  the  --dateform
              option.

       -D, --dateform form
              strptime(3) format for the --not-before and --not-after options, default: %d.%m.%y %T

       -s, --serial hex
              Serial number in hex. It is randomly allocated by default.

       -g, --digest digest
              Digest  to  use  for  signature creation. One of md5, sha1, sha224, sha256, sha384, or sha512. The
              default is determined based on the type and size of the signature key.

       -f, --outform encoding
              Encoding of the created certificate file. Either der (ASN.1 DER) or pem (Base64 PEM), defaults  to
              der.

EXAMPLES

       To  save  repetitive typing, command line options can be stored in files.  Lets assume acert.opt contains
       the following contents:

         --issuercert aacert.der --issuerkey aakey.der --digest sha256 --lifetime 4

       Then the following command can be used to issue an attribute certificate based on  a  holder  certificate
       and the options above:

         pki --acert --options acert.opt --in holder.der --group sales --group finance -f pem
