Function Documentation

isValid() [1/2]

bool base58::isValid ( const char * str, size_t str_size )

noexcept

isValid() [2/2]

bool base58::isValid ( std::string_view str )

noexcept

sizeEncoded()

size_t base58::sizeEncoded

(

std::span< const uint8_t >

data

)

Exceptions

basen::Exception(OVERFLOW)

if there is an overflow

sizeDecoded()

size_t base58::sizeDecoded ( std::string_view str )

noexcept

encode() [1/2]

size_t base58::encode	(	const uint8_t *	data,
		size_t	data_size,
		char *	str,
		size_t	str_size )

Returns

number of leading chars, which should be trimmed

Warning

contain leading zeros, returns count of them

encode() [2/2]

std::string base58::encode

(

std::span< const uint8_t >

data

)

decode() [1/2]

size_t base58::decode	(	const char *	str,
		size_t	str_size,
		uint8_t *	data,
		size_t	data_size )

Returns

number of leading chars, which should be trimmed

Warning

contain leading zeros, returns count of them

decode() [2/2]

std::vector< uint8_t > base58::decode

(

std::string_view

str

)

encodeCheck()

std::string base58::encodeCheck

(

std::span< const uint8_t >

data

)

Parameters

data	vector or span of data which you want to encode

Returns

encoded string + 4 first bytes of double sha256

decodeCheck()

std::vector< uint8_t > base58::decodeCheck

(

std::string_view

str

)

Parameters

str	string or string_view which you want to decode

Returns

decoded data without 4 first bytes of double sha256

Exceptions

basen::Exception(PADDING)	if str size < 4
basen::Exception(CHECKSUM)	checksum incorrect
