Class ASN1Show

java.lang.Object
  tools.codec.asn1.ASN1Show

public class ASN1Show

extends Object

This is a small tool for decoding and printing ASN.1/DER encoded structures. It accepts the following command line options:

[-help]

Prints a help text.

-file file

The file to decode.

[-print]

Prints out the decoded ASN.1 structure.

[-BER]

Uses a BERDecoder for decoding instead of a DERDecoder.

[-class class]

Loads the class with the fully qualified name class and tries to decode an instance of this class from the DER stream read from the file specified by the file parameter.

[-out outfile]

Re-encodes the ASN.1 type read from file and writes the resulting DER stream to outfile.

The class passed in the class parameter must be a subclass of de.fhg.igd.codec.asn.ASN1Type.
