hexlifybx00x01x02

Hexlifybx00x01x02 is a term used in technical writing to denote the hexadecimal representation produced when applying a hex encoding function to the binary sequence consisting of three bytes: 0x00, 0x01, and 0x02. The phrasing combines the function name hexlify with the literal byte sequence indicated in hexadecimal notation, and it is commonly used in examples to illustrate the basic outcome of hex encoding.

In general, hexlify converts binary data to a string of hexadecimal digits. For the byte sequence 0x00, 0x01, 0x02, the canonical hexlify output is the hexadecimal string 00 01 02, typically presented without spaces as 000102. In many programming environments the result is represented as a string of ASCII characters, such as b'000102' in languages that distinguish bytes from text.

Example usage, using the Python standard library, shows that binascii.hexlify(b"\x00\x01\x02") yields b'000102', indicating the mapping from each input byte to two hex digits. Other languages provide similar functionality under names like bytes2hex or hex.

The concept highlights a few properties: the output is deterministic for a given input, each input byte becomes two hex digits, and the process doubles the length of the data in characters. Applications include debugging, data serialization, cryptography, and network protocol representation, where a human-readable hex form of binary data is convenient.
