Public Member Functions
BerTLVBuffer	AddTag (string tag, byte[]? data)
	Adds or updates a tag-value pair in the buffer.
	BerTLVBuffer (byte[]? data, string berTLVTag)
	Constructs a BER-TLV buffer from raw card response data.
byte[]	ConstructDataFieldFromBerTLVBuffer ()
	Constructs complete PIV data field with tag list.
BerTLVBuffer	RemoveTag (string tag)
	Removes a tag-value pair from the buffer.
byte[]	ToByte ()
	Serializes the buffer to BER-TLV formatted byte array.

Public Attributes
Dictionary< string, byte[]>	Content = new()
	Dictionary of TLV components (Tag-Length-Value entries)
bool	IsEmpty = true
	Indicates if the buffer contains no valid TLV data.

Properties
string	BERTLVTag = default! [get, set]
	Main BER-TLV tag identifier for the data object.
byte	GeneralTag = 0x53 [get, set]
	General encapsulation tag (default: 0x53 for Discovery Object)

Detailed Description

Represents a BER-TLV (Binary Encoded Representation Tag-Length-Value) data buffer for PIV (Personal Identity Verification) data object handling.

Implements encoding/decoding of PIV data objects per NIST SP 800-73-4 specifications.
