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
b	01100010
i	01101001
l	01101100
l	01101100
i	01101001
o	01101111
n	01101110
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011000 100110 100101 101100 011011 000110 100101 101111 011011 100111 0011

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
100110	m
100101	l
101100	s
011011	b
000110	G
100101	l
101111	v
011011	b
100111	n
0011	M

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