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
a	01100001
u	01110101
t	01110100
o	01101111
n	01101110
o	01101111
m	01101101
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011000 010111 010101 110100 011011 110110 111001 101111 011011 010111 1001

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010111	X
010101	V
110100	0
011011	b
110110	2
111001	5
101111	v
011011	b
010111	X
1001	k

When combined, these characters form the encoded string: "YXV0b25vbXk="
