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
u	01110101
n	01101110
d	01100100
o	01101111
u	01110101
b	01100010
t	01110100
e	01100101
d	01100100
l	01101100
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 111001 100100 011011 110111 010101 100010 011101 000110 010101 100100 011011 000111 1001

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
111001	5
100100	k
011011	b
110111	3
010101	V
100010	i
011101	d
000110	G
010101	V
100100	k
011011	b
000111	H
1001	k

When combined, these characters form the encoded string: "dW5kb3VidGVkbHk="
