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
              Smartcard  or  TPM  issuer private key object handle in hex format with an optional
              h0x prefix. 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.

       -R, --rsa-padding padding
              Padding to use for RSA signatures. Either pkcs1 or pss, defaults to pkcs1.

       -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
