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
e	01100101
a	01100001
v	01110110
y	01111001
w	01110111
e	01100101
i	01101001
g	01100111
h	01101000
t	01110100

Step 2: Group Bits into 6-bit Chunks

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

011010 000110 010101 100001 011101 100111 100101 110111 011001 010110 100101 100111 011010 000111 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
000110	G
010101	V
100001	h
011101	d
100111	n
100101	l
110111	3
011001	Z
010110	W
100101	l
100111	n
011010	a
000111	H
0100	Q

When combined, these characters form the encoded string: "aGVhdnl3ZWlnaHQ="
