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
n	01101110
t	01110100
a	01100001
i	01101001
n	01101110
m	01101101
e	01100101
n	01101110
t	01110100

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 111101 101110 011101 000110 000101 101001 011011 100110 110101 100101 011011 100111 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
111101	9
101110	u
011101	d
000110	G
000101	F
101001	p
011011	b
100110	m
110101	1
100101	l
011011	b
100111	n
0100	Q

When combined, these characters form the encoded string: "Y29udGFpbm1lbnQ="
