Typedef Documentation

data

typedef std::vector<uint8_t> anonymous_namespace{bech32.cpp}::data

Function Documentation

Cat()

data anonymous_namespace{bech32.cpp}::Cat	(	data	x,
		const data &	y
	)

Concatenate two byte arrays.

CreateChecksum()

data anonymous_namespace{bech32.cpp}::CreateChecksum	(	const std::string &	hrp,
		const data &	values
	)

Create a checksum.

ExpandHRP()

data anonymous_namespace{bech32.cpp}::ExpandHRP

(

const std::string &

hrp

)

Expand a HRP for use in checksum computation.

LowerCase()

unsigned char anonymous_namespace{bech32.cpp}::LowerCase ( unsigned char  c )

inline

Convert to lower case.

PolyMod()

uint32_t anonymous_namespace{bech32.cpp}::PolyMod

(

const data &

v

)

This function will compute what 6 5-bit values to XOR into the last 6 input values, in order to make the checksum 0. These 6 values are packed together in a single 30-bit integer. The higher bits correspond to earlier values.

VerifyChecksum()

bool anonymous_namespace{bech32.cpp}::VerifyChecksum	(	const std::string &	hrp,
		const data &	values
	)

Verify a checksum.
