NAME

siggen - signature gathering routine for Tripwire

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

siggen is a utility that fetches signatures used by Tripwire.

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)
