ASN1_Formatter()

Botan::ASN1_Formatter::ASN1_Formatter ( bool  print_context_specific, size_t  max_depth  )

inline

Parameters

print_context_specific	if true, try to parse nested context specific data.
max_depth	do not recurse more than this many times. If zero, recursion is unbounded.

Member Function Documentation

format()

virtual std::string Botan::ASN1_Formatter::format ( ASN1_Type  type_tag, ASN1_Class  class_tag, size_t  level, size_t  length, std::string_view  value  ) const

protectedpure virtual

This is called for each element

format_bin()

virtual std::string Botan::ASN1_Formatter::format_bin ( ASN1_Type  type_tag, ASN1_Class  class_tag, const std::vector< uint8_t > &  vec  ) const

protectedpure virtual

This is called to format binary elements that we don't know how to convert to a string. The result will be passed as value to format; the tags are included as a hint to aid decoding.

format_bn()

virtual std::string Botan::ASN1_Formatter::format_bn ( const BigInt &  bn ) const

protectedpure virtual

This is called to format integers
