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
i	01101001
m	01101101
p	01110000
r	01110010
o	01101111
v	01110110
e	01100101
d	01100100

Step 2: Group Bits into 6-bit Chunks

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

011010 010110 110101 110000 011100 100110 111101 110110 011001 010110 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010110	W
110101	1
110000	w
011100	c
100110	m
111101	9
110110	2
011001	Z
010110	W
0100	Q

When combined, these characters form the encoded string: "aW1wcm92ZWQ="
