Constructor Details

Asn1Object

public Asn1Object(int tag,
 int length,
 byte[] value)

Construct a ASN.1 TLV. The TLV could be either a constructed or primitive entity.

The first byte in DER encoding is made of following fields,

-------------------------------------------------
|Bit 8|Bit 7|Bit 6|Bit 5|Bit 4|Bit 3|Bit 2|Bit 1|
-------------------------------------------------
|  Class    | CF  |     +      Type             |
-------------------------------------------------
 

• Class: Universal, Application, Context or Private
• CF: Constructed flag. If 1, the field is constructed.
• Type: This is actually called tag in ASN.1. It indicates data type (Integer, String) or a construct (sequence, choice, set).

Parameters:

tag - Tag or Identifier

length - Length of the field

value - Encoded octet string for the field.

Method Details
