Function Documentation

byteToDigit()

char ledger::core::hex::byteToDigit ( uint8_t  , bool  uppercase  )

inline

Turns a single byte (the byte must be lower than 0x10) into a digit.

Exceptions

std::invalid_argument

When encountering an invalid character.

Returns

digitToByte()

uint8_t ledger::core::hex::digitToByte ( char  c )

inline

Turns a single digit into its byte value.

Parameters

c

Returns

toByteArray()

std::vector< uint8_t > ledger::core::hex::toByteArray

(

const std::string &

hexString

)

Decodes the given string into a byte array.

Parameters

hexString

A string of bytes expressed in hexadecimal (e.g. "A0B1").

Exceptions

std::invalid_argument

When encountering an invalid character.

Returns

toString() [1/2]

std::string ledger::core::hex::toString

(

const std::vector< uint8_t > &

data

)

Encodes the given byte array into an hexadecimal string (lowercase).

Parameters

data

Returns

toString() [2/2]

std::string ledger::core::hex::toString	(	const std::vector< uint8_t > &	data,
		bool	uppercase
	)

Encodes the given byte array into an hexadecimal string.

Parameters

data	A byte array
uppercase	True if the output should be expressed in uppercase characters, false otherwise
