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
s	01110011
u	01110101
p	01110000
e	01100101
r	01110010
a	01100001
n	01101110
n	01101110
u	01110101
a	01100001
t	01110100
i	01101001
o	01101111
n	01101110

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 010101 110000 011001 010111 001001 100001 011011 100110 111001 110101 011000 010111 010001 101001 011011 110110 1110

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110111	3
010101	V
110000	w
011001	Z
010111	X
001001	J
100001	h
011011	b
100110	m
111001	5
110101	1
011000	Y
010111	X
010001	R
101001	p
011011	b
110110	2
1110	4

When combined, these characters form the encoded string: "c3VwZXJhbm51YXRpb24="
