About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
g	01100111
m	01101101
a	01100001
i	01101001
l	01101100

Step 2: Group Bits into 6-bit Chunks

The binary string is grouped into 6-bit chunks for Base64 encoding:

011001 110110 110101 100001 011010 010110 1100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
110110	2
110101	1
100001	h
011010	a
010110	W
1100	w

When combined, these characters form the encoded string: "Z21haWw="
