NAME
siggen - signature gathering routine for Tripwire

SYNOPSIS
siggen siggen [-0123456789aqv] [ file ... ]

DESCRIPTION

siggen is a utility that fetches signatures used by Tripwire.

OPTIONS

When run without any arguments, siggen collects all the signatures on the specified files in a verbose manner.

When no arguments are given, siggen reads from standard input.

-h  prints the signature in hexadecimal instead of base-64.

-q  Quiet mode. Prints out all signatures in one line with no extraneous information.

-a  Generates all signatures. (default)

-v  Verbose mode. (default)

-0  signature 0 - generates null signature

-1  signature 1 - generates MD5, the RSA Data Security, Inc. Message Digesting Algorithm.

-2  signature 2 - generates Snefru, the Xerox Secure Hash Function.

-3  signature 3 - generates CRC-32, POSIX 1003.2 compliant 32-bit Cyclic Redundancy Check.

-4  signature 4 - generates CRC-16, the standard (non-CCITT) 16-bit Cyclic Redundancy Check.

-5  signature 5 - generates MD4, the RSA Data Security, Inc. Message Digesting Algorithm.

-6  signature 6 - generates MD2, the RSA Data Security, Inc. Message Digesting Algorithm.

-7  signature 7 - generates SHA, the NIST Secure Hash Algorithm (NIST FIPS 180)

-8  signature 8 - generates Haval, a 128-bit signature code

-9  signature 9 - generates null signature (reserved for future expansion)
