This constructor initializes an octet string from the given byte array.

Parameters

data	Byte array containing an octet string in binary form.

◆ Asn1OctetString() [3/4]

Asn1OctetString	(	byte []	data,

Parameters

data	Byte array containing an octet string in binary form.
offset	The offset in array at which to begin copy.
nbytes	Number of bytes to copy from target array

◆ Asn1OctetString() [4/4]

Asn1OctetString ( System.String value )

This constructor parses the given ASN.1 value text (either a binary or hex data string) and assigns the values to the internal bit string.

Examples of valid value formats are as follows:

Binary string: '11010010111001'B

Hex string: '0fa56920014abc'H

Char string: 'abcdefg'
