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
f	01100110
f	01100110
i	01101001
r	01110010
m	01101101
a	01100001
t	01110100
i	01101001
v	01110110
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 011001 100110 011010 010111 001001 101101 011000 010111 010001 101001 011101 100110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
011001	Z
100110	m
011010	a
010111	X
001001	J
101101	t
011000	Y
010111	X
010001	R
101001	p
011101	d
100110	m
0101	U

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