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
g	01100111
r	01110010
o	01101111
u	01110101
p	01110000

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 010101 100010 011001 110111 001001 101111 011101 010111 0000

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110111	3
010101	V
100010	i
011001	Z
110111	3
001001	J
101111	v
011101	d
010111	X
0000	A

When combined, these characters form the encoded string: "c3ViZ3JvdXA="
