pack 'C'
, pack 'N'
and pack 'H*'
are used to create a sequence of bytes.
my $bytes = pack('C', $uint8);
# Array of bytes
var bytes = [];
bytes.push(uint8);
# String of bytes
var bytes = "";
bytes += String.fromCharCode(uint8);
my $bytes = pack('N', $uint32);
# Array of bytes
var bytes = [];
bytes.push((uint32 >> 24) & 0xFF);
bytes.push((uint32 >> 16) & 0xFF);
bytes.push((uint32 >> 8) & 0xFF);
bytes.push((uint32 ) & 0xFF);
# String of bytes
var bytes = "";
bytes += String.fromCharCode((uint32 >> 24) & 0xFF);
bytes += String.fromCharCode((uint32 >> 16) & 0xFF);
bytes += String.fromCharCode((uint32 >> 8) & 0xFF);
bytes += String.fromCharCode((uint32 ) & 0xFF);
my $bytes = pack('H*', $hex_str);
# Array of bytes
function hexToBytes(hex) {
var bytes = [];
for (var c = 0; c < hex.length; c += 2)
bytes.push(parseInt(hex.substr(c, 2), 16));
return bytes;
}
# String of bytes
function hexToBytes(hex) {
var bytes = "";
for (var c = 0; c < hex.length; c += 2)
bytes += String.fromCharCode(parseInt(hex.substr(c, 2), 16));
return bytes;
