virtualsmartcard.utils._make_byte_property(prop)

Make a byte property(). This is meta code.

virtualsmartcard.utils.hexdump(data, indent=0, short=False, linelen=16, offset=0)

Generates a nice hexdump of data and returns it. Consecutive lines will be indented with indent spaces. When short is true, will instead generate hexdump without adresses and on one line.

Examples: hexdump(b’A’) -> ‘0000: 00 41 .A ‘ hexdump(b’A’, short=True) -> ‘00 41 (.A)’

virtualsmartcard.utils.inttostring(i, length=None, len_extendable=False)
