OCRA_TOOL(8)		  BSD System Manager's Manual		  OCRA_TOOL(8)

NAME
     ocra_tool — create and view OCRA credential files

SYNOPSIS
     ocra_tool info -f credential_file
     ocra_tool init -f credential_file -s suite_string -k key [-c counter]
	       [-p pin | -P pinhash] [-w counter_window] [-t timestamp_offset]

DESCRIPTION
     The ocra_tool utility is used to initialize and view OCRA credential
     files used by the pam_ocra(8) authentication service module for PAM.

     info  Show content of OCRA credential file.

	   -f credential_file
		  the OCRA credential file.

     init  Initialize OCRA credential file.

	   -f credential_file
		  the OCRA credential file.

	   -s suite_string
		  OCRA suite string.

	   -k key
		  specified as hexadecimal string.

	   -c counter
		  If the suite_string requires a counter parameter, counter is
		  the initial counter value. If counter begins with '0x' it
		  will be interpreted as hexadecimal number.

	   -p pin | -P pinhash
		  If the suite_string requires a pin-hash parameter, it is
		  either set as hexadecimal string pinhash or calculated from
		  pin using the pin-hash algorithm in suite_string.

	   -w counter_window
		  If the suite_string requires a counter parameter,
		  counter_window specifies the maximum number of verify
		  attempts pam_ocra(8) will make (while incrementing the
		  counter value).  This parameter is optional.

	   -t timestamp_offset
		  If the suite_string requires a timestamp parameter,
		  timestamp_offset specifies the number of timestamp steps
		  pam_ocra(8) will make while verifying a response. The verify
		  process will start at (current_timestamp - timestamp_offset)
		  and end at (current_timestamp + timestamp_offset).  This
		  parameter is optional.

EXAMPLE
     $ ocra_tool init -f ~/.ocra -s OCRA-1:HOTP-SHA1-6:C-QN08-PSHA1 \
	     -k 00112233445566778899aabbccddeeff00112233 \
	     -c 10 -p 1234 -w 50

     $ ocra_tool info -f ~/.ocra
     suite:	     OCRA-1:HOTP-SHA1-6:C-QN08-PSHA1
     key:	     0x00112233445566778899aabbccddeeff00112233
     counter:	     0x000000000000000a
     counter_window: 50
     pin_hash:	     0x7110eda4d09e062aa5e4a390b0a572ac0d2c0220
