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
b	01100010
t	01110100
o	01101111
t	01110100
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 010101 100010 011101 000110 111101 110100 011000 010110 1100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110111	3
010101	V
100010	i
011101	d
000110	G
111101	9
110100	0
011000	Y
010110	W
1100	w

When combined, these characters form the encoded string: "c3VidG90YWw="
