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
a	01100001
t	01110100
c	01100011
h	01101000

Step 2: Group Bits into 6-bit Chunks

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

011000 100110 000101 110100 011000 110110 1000

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
100110	m
000101	F
110100	0
011000	Y
110110	2
1000	g

When combined, these characters form the encoded string: "YmF0Y2g="
