About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: Two '=' characters are added when the input length modulo 3 equals 1. This happens because the input length leaves a remainder of 1 when divided by 3, indicating that two more bytes are needed to complete the 3-byte group. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
a	01100001
p	01110000
p	01110000
r	01110010
o	01101111
x	01111000
i	01101001
m	01101101
a	01100001
t	01110100
e	01100101
l	01101100
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011000 010111 000001 110000 011100 100110 111101 111000 011010 010110 110101 100001 011101 000110 010101 101100 011110 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010111	X
000001	B
110000	w
011100	c
100110	m
111101	9
111000	4
011010	a
010110	W
110101	1
100001	h
011101	d
000110	G
010101	V
101100	s
011110	e
01	Q

When combined, these characters form the encoded string: "YXBwcm94aW1hdGVseQ=="
