Constructor Detail

Asn1DerDecodeBuffer

public Asn1DerDecodeBuffer(byte[] msgdata)

This constructor creates a DER decode buffer object that references an encoded ASN.1 message.

Parameters:

msgdata - Byte array containing an encoded ASN.1 message.

Asn1DerDecodeBuffer

public Asn1DerDecodeBuffer(java.io.InputStream istream)

This constructor creates a DER decode buffer object that references an encoded ASN.1 message. In this case, the message is passed in using an InputStream object.

Parameters:

istream - Input stream containing an encoded ASN.1 message.
