Functions
unsigned	hex2bytes (char *s, uint8_t **dest)
	convert string representation of hex value into array of bytes
const char *	bin2str (const uint8_t *data, uint32_t len)
	Create printable representation of byte string. If data in set are ASCII characters, then representation is given string, else the format is "0x...".
void	hexalize (uint8_t **data, unsigned *len)
	If data passed to function are in format "0x..." then convert such valu to correspondig byte array, else leave text string.
BIGNUM *	HexToBignum (const uint8_t *hex, uint32_t len)
	Convert a hex representation to BIGNUM.
uint8_t *	Clone (const uint8_t *data, uint32_t len)
	Clone a buffer.
void	PrintBuffer (unsigned char *buf, unsigned long len)
	Print a binary buffer in hex string format.
void	PrintBignum (const BIGNUM *a)
uint32_t	StringToIP (char *str_ip)
	Convert IP address from string to binary format e.g. 1.2.34 --> 0x04030201.
char *	IPToString (uint32_t ip)
	Convert an IP addr from binary format to string e.g. 0x04030201 --> 1.2.3.4.

Function Documentation

const char* bin2str (  const uint8_t *  data, uint32_t  len )

Create printable representation of byte string. If data in set are ASCII characters, then representation is given string, else the format is "0x...". Parameters: data  byte string len  length of data Returns: pointer to static buffer which contains printable representation of data

uint8_t* Clone (  const uint8_t *  data, uint32_t  len )

Clone a buffer. Parameters: *data  data to clone len  data length Returns: pointer to new allocated memory with copy of data.

unsigned hex2bytes (  char *  s, uint8_t **  dest )

convert string representation of hex value into array of bytes Parameters: *s  string representation **dest  result array of bytes Returns: length of dest

void hexalize (  uint8_t **  data, unsigned *  len )

If data passed to function are in format "0x..." then convert such valu to correspondig byte array, else leave text string. Parameters: **data  data to convert/result *len  len of result data

BIGNUM* HexToBignum (  const uint8_t *  hex, uint32_t  len )

Convert a hex representation to BIGNUM. Parameters: *hex  hex representation len  length of hex Returns: BIGNUM value of hex

char* IPToString (  uint32_t  ip  )

Convert an IP addr from binary format to string e.g. 0x04030201 --> 1.2.3.4. Parameters: ip  32-bit value of IP address Returns: string representation of IP address

void PrintBignum (  const BIGNUM *  a  )

void PrintBuffer (  unsigned char *  buf, unsigned long  len )

Print a binary buffer in hex string format. Parameters: *buf  buffer len  buffer length

uint32_t StringToIP (  char *  str_ip  )

Convert IP address from string to binary format e.g. 1.2.34 --> 0x04030201. Parameters: *str_ip  string with IP address Returns: 32-bit value of IP address
