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 contains OIDs
commonly used.
