from_hex()

static std::vector<unsigned char> dibigd::Bvec::from_hex ( std::string  s )

static

Decodes a hex-encoded string to a byte vector.

Parameters

s	String of hex digits (with or without a '0x' prefix)

Returns

Decoded byte vector.

Remarks

Leading zeros are significant.

Exceptions

std::invalid_argument

exception if an invalid character is found.

print_hex() [1/2]

static void dibigd::Bvec::print_hex ( std::string  prefix, std::vector< unsigned char >  barr, std::string  sep = " "  )

static

Print contents of byte array vector in hex with prefix.

Parameters

prefix	Prefix string.
barr	A vector of bytes.
sep	Optional separator string (default=" ", space)

print_hex() [2/2]

static void dibigd::Bvec::print_hex ( std::vector< unsigned char >  barr, std::string  sep = " "  )

static

Print contents of byte array vector in hex.

Parameters

barr	A vector of bytes.
sep	Optional separator string (default=" ") BigDigit b(0xdeadbeef); std::vector<unsigned char> barr = b.to_octets(); Bvec::print_hex(barr); // de ad be ef Bvec::print_hex(barr, ""); // deadbeef Bvec::print_hex(barr, " : "); // de : ad : be : ef // Specify exact length barr = b.to_octets(6); Vec::print_hex(barr); // 00 00 de ad be ef
