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
i	01101001
r	01110010
p	01110000
o	01101111
r	01110010
t	01110100
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 100101 110010 011100 000110 111101 110010 011101 000111 0011

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
100101	l
110010	y
011100	c
000110	G
111101	9
110010	y
011101	d
000111	H
0011	M

When combined, these characters form the encoded string: "YWlycG9ydHM="
