Detailed Description

This is a container class for holding the components of an ASN.1 bit string value.

Member Enumeration Documentation

◆ StringFormat

enum StringFormat

strong

Defines possible string fomrats.

The HEX constant describes the string format as hex digit value (e.g. 0123456789ABCDEF).

The BITS constant describes the string format as binary digit value (e.g. only 0 and 1 digits).

The ASN1VALUE constant describes the string format as hex or binary digit value. The binary string value will end with letter 'B' and hex string value will end with letter 'H' (e.g. '0101'B or '11'H ). If the number of bits is less than or equal to 16, than it will be printed as Binary digits, else as Hex digits.
