NAME
       dumpasn1 - ASN.1 object dump/syntax check program

SYNOPSIS
       dumpasn1 [options] file

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.

OPTIONS
       -      Take input from stdin (some options may not work properly).

       -number
	      Start number bytes into the file.

       --     End of arg list.

       -a     Print all data in long data blocks, not just the first 128 bytes.

       -c file
	      Read Object Identifier info from alternate config file (values will override equivalents in global config file)

       -d     Print dots to show column alignment.

       -e     Don't print encapsulated data inside OCTET/BIT STRINGs.

       -f file
	      Dump object at offset -number to file (allows data to be extracted from encapsulating objects)

       -h     Hex dump object header (tag+length) before the decoded output

       -hh    Same as -h but display more of the object as hex data.

       -l     Long format, display extra info about Object Identifiers.

       -o     Don't check validity of character strings hidden in octet strings.

       -p     Pure ASN.1 output without encoding information.

       -r     Print bits in BIT STRING as encoded in reverse order

       -s     Syntax check only, don't dump ASN.1 structures.

       -t     Display text values next to hex dump of data.

       -u     Don't format UTCTime/GeneralizedTime string data.

       -w     Set output width (default 80).

       -x     Display size and offset in hex not decimal.

FILES
       ./dumpasn1.cfg, $HOME/.dumpasn1.cfg, /etc/dumpasn1/dumpasn1.cfg: This is the configuration file, it will be searched in this order. It con-
       tains OIDs commonly used.
