.TH dumpasn1 1 User Manuals .SH NAME dumpasn1 \- ASN.1 object dump/syntax check program .SH SYNOPSIS \fB/usr/bin/dumpasn1 [\fIoptions\fB] \fIfile\fB \f1 .SH DESCRIPTION An ASN.1 object dump program which will dump data encoded using any of the ASN.1 encoding rules in a variety of user-specified formats. .SH OPTIONS .TP \fB-\f1 Take input from stdin (some options may not work properly). .TP \fB-\f1\fInumber\f1 Start \fInumber\f1 bytes into the file. .TP \fB--\f1 End of arg list. .TP \fB-a\f1 Print all data in long data blocks, not just the first 128 bytes. .TP \fB-c\f1 \fIfile\f1 Read Object Identifier info from alternate config file (values will override equivalents in global config file) .TP \fB-d\f1 Print dots to show column alignment. .TP \fB-e\f1 Don't print encapsulated data inside OCTET/BIT STRINGs. .TP \fB-f\f1 \fIfile\f1 Dump object at offset -\fInumber\f1 to file (allows data to be extracted from encapsulating objects) .TP \fB-h\f1 Hex dump object header (tag+length) before the decoded output .TP \fB-hh\f1 Same as -h but display more of the object as hex data. .TP \fB-l\f1 Long format, display extra info about Object Identifiers. .TP \fB-o\f1 Don't check validity of character strings hidden in octet strings. .TP \fB-p\f1 Pure ASN.1 output without encoding information. .TP \fB-r\f1 Print bits in BIT STRING as encoded in reverse order .TP \fB-s\f1 Syntax check only, don't dump ASN.1 structures. .TP \fB-t\f1 Display text values next to hex dump of data. .TP \fB-u\f1 Don't format UTCTime/GeneralizedTime string data. .TP \fB-x\f1 Display size and offset in hex not decimal. .SH FILES \fI./dumpasn1.cfg, $HOME/.dumpasn1.cfg, /etc/dumpasn1/dumpasn1.cfg\f1: This is the configuration file, it will be searched in this order. It contains OIDs commonly used. .SH AUTHORS qoute from Peter Gutmann: ASN.1 object dumping code, copyright Peter Gutmann <pgut001@cs.auckland.ac.nz>, based on ASN.1 dump program by David Kemp <dpkemp@missi.ncsc.mil>, with contributions from various people including Matthew Hamrick <hamrick@rsa.com>, Bruno Couillard <bcouillard@chrysalis-its.com>, Hallvard Furuseth <h.b.furuseth@usit.uio.no>, Geoff Thorpe <geoff@raas.co.nz>, David Boyce <d.boyce@isode.com>, John Hughes <john.hughes@entegrity.com>, Life is hard, and then you die <ronald@trustpoint.com>, Hans-Olof Hermansson <hans-olof.hermansson@postnet.se>, Tor Rustad <Tor.Rustad@bbs.no>, Kjetil Barvik <kjetil.barvik@bbs.no>, James Sweeny <jsweeny@us.ibm.com>, and several other people whose names I've misplaced. dumpasn1 is available at \fBhttp://www.cs.auckland.ac.nz/~pgut001/\f1 .SH COMMENTS This man page was written using \fBxml2man(1)\f1 by Oliver Kurth for Debian.
