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
t	01110100
m	01101101
o	01101111
s	01110011
p	01110000
h	01101000
e	01100101
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:

011000 010111 010001 101101 011011 110111 001101 110000 011010 000110 010101 110010 011010 010110 0011

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010111	X
010001	R
101101	t
011011	b
110111	3
001101	N
110000	w
011010	a
000110	G
010101	V
110010	y
011010	a
010110	W
0011	M

When combined, these characters form the encoded string: "YXRtb3NwaGVyaWM="
