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
h	01101000
y	01111001
d	01100100
r	01110010
o	01101111
g	01100111
e	01100101
n	01101110

Step 2: Group Bits into 6-bit Chunks

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

011010 000111 100101 100100 011100 100110 111101 100111 011001 010110 1110

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
000111	H
100101	l
100100	k
011100	c
100110	m
111101	9
100111	n
011001	Z
010110	W
1110	4

When combined, these characters form the encoded string: "aHlkcm9nZW4="
