About Base16 / Hexadecimal Decoding

Base16 Encoder

Base16 decoding, also known as hexadecimal decoding, is the process of converting a Base16-encoded string back into its original binary representation.

Let's take the Base16-encoded string 48656C6C6F as an example. Each pair of characters in this string represents a Base16 symbol, which corresponds to 4 bits or half a byte of binary data.

To decode this Base16 string, we need to convert each Base16 symbol back into its corresponding 4-bit binary representation.

Let's break down the Base16 string "48656C6C6F" into pairs:

48 65 6C 6C 6F

Next, we need to convert each pair of Base16 symbols into its corresponding 4-bit binary representation. We can use the following table for this conversion:

Hexadecimal Binary
0 0000
1 0001
2 0010
3 0011
4 0100
5 0101
6 0110
7 0111
8 1000
9 1001
A 1010
B 1011
C 1100
D 1101
E 1110
F 1111

Using this table, we can convert each pair of Base16 symbols into their corresponding binary representation:

01001000 01100101 01101100 01101100 01101111

Now, we have the binary representation of the original data. To convert this binary back into text, we need to interpret it according to a specific character encoding, such as UTF-8 or ASCII.

Using ASCII encoding, each 8-bit binary value represents a single character.

Binary: 01001000 01100101 01101100 01101100 01101111

Decoding each 8-bit binary value using ASCII encoding gives us the characters: H e l l o

Therefore, when decoding the Base16-encoded string 48656C6C6F using ASCII encoding, we get the original text Hello.
