Detailed Description

This class handles the decoding of ASN.1 messages as specified in the Distinguished Encoding Rules (DER) as documented in the ITU-T X.690 standard.

Constructor & Destructor Documentation

◆ Asn1DerDecodeBuffer() [1/2]

Asn1DerDecodeBuffer ( byte []  msgdata)

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

Parameters
msgdataByte array containing an encoded ASN.1 message.

◆ Asn1DerDecodeBuffer() [2/2]

Asn1DerDecodeBuffer ( System.IO.Stream  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 System.IO.Stream object.

Parameters
istreamInput stream containing an encoded ASN.1 message.
