NAME

6       dumpasn1 - ASN.1 object dump/syntax check program
7

SYNOPSIS

9       /usr/bin/dumpasn1 [options] file
10

DESCRIPTION

12       An  ASN.1 object dump program which will dump data encoded using any of
13       the ASN.1 encoding rules in a variety of user-specified formats.
14

OPTIONS

16       -      Take input from stdin (some options may not work properly).
17
18       -number
19              Start number bytes into the file.
20
21       --     End of arg list.
22
23       -a     Print all data in long data  blocks,  not  just  the  first  128
24              bytes.
25
26       -c file
27              Read  Object  Identifier info from alternate config file (values
28              will override equivalents in global config file)
29
30       -d     Print dots to show column alignment.
31
32       -e     Don't print encapsulated data inside OCTET/BIT STRINGs.
33
34       -f file
35              Dump object at  offset  -number  to  file  (allows  data  to  be
36              extracted from encapsulating objects)
37
38       -h     Hex dump object header (tag+length) before the decoded output
39
40       -hh    Same as -h but display more of the object as hex data.
41
42       -l     Long format, display extra info about Object Identifiers.
43
44       -o     Don't  check  validity  of  character  strings  hidden  in octet
45              strings.
46
47       -p     Pure ASN.1 output without encoding information.
48
49       -r     Print bits in BIT STRING as encoded in reverse order
50
51       -s     Syntax check only, don't dump ASN.1 structures.
52
53       -t     Display text values next to hex dump of data.
54
55       -u     Don't format UTCTime/GeneralizedTime string data.
56
57       -x     Display size and offset in hex not decimal.

FILES

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