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
p	01110000
e	01100101
r	01110010
t	01110100
u	01110101
r	01110010
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011000 010111 000001 100101 011100 100111 010001 110101 011100 100110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010111	X
000001	B
100101	l
011100	c
100111	n
010001	R
110101	1
011100	c
100110	m
0101	U

When combined, these characters form the encoded string: "YXBlcnR1cmU="
