◆ ASN1_Pretty_Printer()

Botan::ASN1_Pretty_Printer::ASN1_Pretty_Printer	(	size_t	print_limit = 4096,
		size_t	print_binary_limit = 2048,
		bool	print_context_specific = true,
		size_t	initial_level = 0,
		size_t	value_column = 60,
		size_t	max_depth = 64,
		bool	require_der = false )

inlineexplicit

Parameters

print_limit	strings larger than this are not printed
print_binary_limit	binary strings larger than this are not printed
print_context_specific	if true, try to parse nested context specific data.
initial_level	the initial depth (0 or 1 are the only reasonable values)
value_column	ASN.1 values are lined up at this column in output
max_depth	do not recurse more than this many times. If zero, recursion is unbounded.
require_der	if true then non-canonical BER data is rejected
