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
i	01101001
s	01110011
t	01110100
o	01101111
r	01110010
i	01101001
c	01100011

Step 2: Group Bits into 6-bit Chunks

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

011010 000110 100101 110011 011101 000110 111101 110010 011010 010110 0011

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
000110	G
100101	l
110011	z
011101	d
000110	G
111101	9
110010	y
011010	a
010110	W
0011	M

When combined, these characters form the encoded string: "aGlzdG9yaWM="
