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
c	01100011
o	01101111
m	01101101
p	01110000
o	01101111
s	01110011
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 110110 111101 101101 011100 000110 111101 110011 011001 010111 0010

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
111101	9
101101	t
011100	c
000110	G
111101	9
110011	z
011001	Z
010111	X
0010	I

When combined, these characters form the encoded string: "Y29tcG9zZXI="
