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
a	01100001
t	01110100
e	01100101
g	01100111
o	01101111
r	01110010
i	01101001
z	01111010
e	01100101
d	01100100

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 000101 110100 011001 010110 011101 101111 011100 100110 100101 111010 011001 010110 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
000101	F
110100	0
011001	Z
010110	W
011101	d
101111	v
011100	c
100110	m
100101	l
111010	6
011001	Z
010110	W
0100	Q

When combined, these characters form the encoded string: "Y2F0ZWdvcml6ZWQ="
