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
u	01110101
t	01110100
h	01101000
o	01101111
r	01110010
i	01101001
z	01111010
a	01100001
t	01110100
i	01101001
o	01101111
n	01101110

Step 2: Group Bits into 6-bit Chunks

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

011000 010111 010101 110100 011010 000110 111101 110010 011010 010111 101001 100001 011101 000110 100101 101111 011011 10

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010111	X
010101	V
110100	0
011010	a
000110	G
111101	9
110010	y
011010	a
010111	X
101001	p
100001	h
011101	d
000110	G
100101	l
101111	v
011011	b
10	g

When combined, these characters form the encoded string: "YXV0aG9yaXphdGlvbg=="
