=head1 DESCRIPTION
a file containing additional OBJECT IDENTIFIERs (OIDs). The format of this
file is described in the NOTES section below.
+=item B<-dump>
+
+dump unknown data in hex format.
+
+=item B<-dlimit num>
+
+like B<-dump>, but only the first B<num> bytes are output.
+
=item B<-strparse offset>
parse the contents octets of the ASN.1 object starting at B<offset>. This
option can be used multiple times to "drill down" into a nested structure.
+=item B<-genstr string>, B<-genconf file>
+
+generate encoded data based on B<string>, B<file> or both using
+L<ASN1_generate_nconf(3)|ASN1_generate_nconf(3)> format. If B<file> only is
+present then the string is obtained from the default section using the name
+B<asn1>. The encoded data is passed through the ASN1 parser and printed out as
+though it came from a file, the contents can thus be examined and written to a
+file using the B<out> option.
+
+=item B<-strictpem>
+
+If this option is used then B<-inform> will be ignored. Without this option any
+data in a PEM format input file will be treated as being base64 encoded and
+processed whether it has the normal PEM BEGIN and END markers or not. This
+option will ignore any data prior to the start of the BEGIN marker, or after an
+END marker in a PEM file.

+=head1 EXAMPLES
+
+Parse a file:
+
+ openssl asn1parse -in file.pem
+
+Parse a DER file:
+
+ openssl asn1parse -inform DER -in file.der
+
+Generate a simple UTF8String:
+
+ openssl asn1parse -genstr 'UTF8:Hello World'
+
+Generate and write out a UTF8String, don't print parsed output:
+
+ openssl asn1parse -genstr 'UTF8:Hello World' -noout -out utf8.der
+
+Generate using a config file:
+
+ openssl asn1parse -genconf asn1.cnf -noout -out asn1.der
+
+Example config file:
+
+ asn1=SEQUENCE:seq_sect
+
+ [seq_sect]
+
+ field1=BOOL:TRUE
+ field2=EXP:0, UTF8:some random string
