It can also be used to extract data from \s-1ASN.1\s0 formatted data. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-inform\fR \fBDER|PEM\fR" 4 .IX Item "-inform DER|PEM" the input format. \fB\s-1DER\s0\fR is binary format and \fB\s-1PEM\s0\fR (the default) is base64 encoded. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" the input file, default is standard input .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" output file to place the \s-1DER\s0 encoded data into. If this option is not present then no data will be output. This is most useful when combined with the \fB\-strparse\fR option. .IP "\fB\-noout\fR" 4 .IX Item "-noout" don't output the parsed version of the input file. .IP "\fB\-offset number\fR" 4 .IX Item "-offset number" starting offset to begin parsing, default is start of file. .IP "\fB\-length number\fR" 4 .IX Item "-length number" number of bytes to parse, default is until end of file. .IP "\fB\-i\fR" 4 .IX Item "-i" indents the output according to the \*(L"depth\*(R" of the structures. .IP "\fB\-oid filename\fR" 4 .IX Item "-oid filename" a file containing additional \s-1OBJECT\s0 IDENTIFIERs (OIDs). The format of this file is described in the \s-1NOTES\s0 section below. .IP "\fB\-dump\fR" 4 .IX Item "-dump" dump unknown data in hex format. .IP "\fB\-dlimit num\fR" 4 .IX Item "-dlimit num" like \fB\-dump\fR, but only the first \fBnum\fR bytes are output. .IP "\fB\-strparse offset\fR" 4 .IX Item "-strparse offset" parse the contents octets of the \s-1ASN.1\s0 object starting at \fBoffset\fR. This option can be used multiple times to \*(L"drill down\*(R" into a nested structure. .IP "\fB\-genstr string\fR, \fB\-genconf file\fR" 4 .IX Item "-genstr string, -genconf file" generate encoded data based on \fBstring\fR, \fBfile\fR or both using \&\fIASN1_generate_nconf\fR\|(3) format. If \fBfile\fR only is present then the string is obtained from the default section using the name \&\fBasn1\fR. The encoded data is passed through the \s-1ASN1\s0 parser and printed out as though it came from a file, the contents can thus be examined and written to a file using the \fBout\fR option. .SS "\s-1OUTPUT\s0" .IX Subsection "OUTPUT" The output will typically contain lines like this: .PP .Vb 1 \& 0:d=0 hl=4 l= 681 cons: SEQUENCE .Ve .PP \&..... .PP .Vb 10 \& 229:d=3 hl=3 l= 141 prim: BIT STRING \& 373:d=2 hl=3 l= 162 cons: cont [ 3 ] \& 376:d=3 hl=3 l= 159 cons: SEQUENCE \& 379:d=4 hl=2 l= 29 cons: SEQUENCE \& 381:d=5 hl=2 l= 3 prim: OBJECT :X509v3 Subject Key Identifier \& 386:d=5 hl=2 l= 22 prim: OCTET STRING \& 410:d=4 hl=2 l= 112 cons: SEQUENCE \& 412:d=5 hl=2 l= 3 prim: OBJECT :X509v3 Authority Key Identifier \& 417:d=5 hl=2 l= 105 prim: OCTET STRING \& 524:d=4 hl=2 l= 12 cons: SEQUENCE .Ve .PP \&..... .PP This example is part of a self signed certificate. Each line starts with the offset in decimal. \fBd=XX\fR specifies the current depth. The depth is increased within the scope of any \s-1SET\s0 or \s-1SEQUENCE. \s0\fBhl=XX\fR gives the header length (tag and length octets) of the current type. \fBl=XX\fR gives the length of the contents octets. .PP The \fB\-i\fR option can be used to make the output more readable. .PP Some knowledge of the \s-1ASN.1\s0 structure is needed to interpret the output. .PP In this example the \s-1BIT STRING\s0 at offset 229 is the certificate public key. The contents octets of this will contain the public key information. This can be examined using the option \fB\-strparse 229\fR to yield: .PP .Vb 3 \& 0:d=0 hl=3 l= 137 cons: SEQUENCE \& 3:d=1 hl=3 l= 129 prim: INTEGER :E5D21E1F5C8D208EA7A2166C7FAF9F6BDF2059669C60876DDB70840F1A5AAFA59699FE471F379F1DD6A487E7D5409AB6A88D4A9746E24B91D8CF55DB3521015460C8EDE44EE8A4189F7A7BE77D6CD3A9AF2696F486855CF58BF0EDF2B4068058C7A947F52548DDF7E15E96B385F86422BEA9064A3EE9E1158A56E4A6F47E5897 \& 135:d=1 hl=2 l= 3 prim: INTEGER :010001 .Ve .SH "NOTES" .IX Header "NOTES" If an \s-1OID\s0 is not part of OpenSSL's internal table it will be represented in numerical form (for example 1.2.3.4). The file passed to the \fB\-oid\fR option allows additional OIDs to be included. Each line consists of three columns, the first column is the \s-1OID\s0 in numerical format and should be followed by white space. The second column is the \*(L"short name\*(R" which is a single word followed by white space. The final column is the rest of the line and is the \&\*(L"long name\*(R". \fBasn1parse\fR displays the long name.
