What is Hexadecimal

Hexadecimal is a numeral system that uses 0-9 and A-F, a total of 16 characters to represent values. Features include:

Each digit's weight is a power of 16.
It conveniently represents binary data, as four binary digits correspond to one hex digit.
For example, decimal 10 is A in hex, decimal 15 is F, and decimal 16 is 10.

Hexadecimal Encoding Algorithm

Starting from the least significant bit, group every 4 binary digits.
Convert each group to its corresponding hex digit.
For example, binary number 11010110 can be split into two groups: 1101 and 0110. 1101 corresponds to hex D, and 0110 corresponds to hex 6, so the binary number's hex representation is D6.

Go Implementation

hex.EncodeToString([]byte("11010110"))
