NAME
dumpasn1 - ASN.1 object dump/syntax check program
SYNOPSIS
/usr/bin/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
contains OIDs commonly used.
