Detailed Description

Utility Functions.

The Util class implements as set of utility functions. Some of the static methods may be useful for applications that work with the CryptoServer.

store_int2()

void store_int2 ( unsigned int  val, unsigned char *  buf  )

static

Stores a 2-byte integer in to a character buffer. The integer is stored in big endian order.

Parameters

val	Integer value to be stored (unsigned).
buf	Byte array into which the integer is stored.

store_int3()

void store_int3 ( unsigned int  val, unsigned char *  buf  )

static

Stores a 3-byte integer in to a character buffer. The integer is stored in big endian order.

Parameters

val	Integer value to be stored (unsigned).
buf	Byte array into which the integer is stored.

store_int4()

void store_int4 ( unsigned int  val, unsigned char *  buf  )

static

Stores a 4-byte integer in to a character buffer. The integer is stored in big endian order.

Parameters

val	Integer value to be stored (unsigned).
buf	Byte array into which the integer is stored.

load_int2()

unsigned int load_int2 ( const unsigned char *  buf )

static

Loads a 2-byte integer from a character buffer. The integer must be stored in big endian order.

Parameters

buf	Buffer from which the integer is loaded.

Returns

Integer value loaded (unsigned).

load_int3()

unsigned int load_int3 ( const unsigned char *  buf )

static

Loads a 3-byte integer from a character buffer. The integer must be stored in big endian order.

Parameters

buf	Buffer from which the integer is loaded.

Returns

Integer value loaded (unsigned).

load_int4()

unsigned int load_int4 ( const unsigned char *  buf )

static

Loads a 4-byte integer from a character buffer. The integer must be stored in big endian order.

Parameters

buf	Buffer from which the integer is loaded.

Returns

Integer value loaded (unsigned).

xtrace() [1/3]

void xtrace ( FILE *  fp, const char *  prefix, const char *  text, const void *  data, int  len  )

static

Dumps binary data to a file stream. The binary data is converted to hexadecimal notation.

Parameters

fp	target file stream
prefix	string to print before each line
text	tag (optional)
data	pointer to binary data
len	length of binary data

xtrace() [2/3]

void xtrace ( const char *  text, const void *  data, int  len  )

static

Dumps binary data to stdout. The binary data is converted to hexadecimal notation.

Parameters

text	tag (optional)
data	pointer to binary data
len	length of binary data

xtrace() [3/3]

void xtrace ( const char *  text, const ByteArray &  ba  )

static

Dumps binary data to stdout. The binary data is converted to hexadecimal notation.

Parameters

text	tag (optional)
ba	byte arry to be dumped
