.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.
