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
a	01100001
f	01100110
t	01110100
e	01100101
r	01110010

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 011001 110100 011001 010111 0010

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
011001	Z
110100	0
011001	Z
010111	X
0010	I

When combined, these characters form the encoded string: "YWZ0ZXI="
