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
d	01100100
d	01100100
e	01100101
n	01101110
d	01100100
u	01110101
m	01101101

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 010001 100100 011001 010110 111001 100100 011101 010110 1101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
010001	R
100100	k
011001	Z
010110	W
111001	5
100100	k
011101	d
010110	W
1101	0

When combined, these characters form the encoded string: "YWRkZW5kdW0="
