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
r	01110010
e	01100101
s	01110011
i	01101001
d	01100100
u	01110101
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011100 100110 010101 110011 011010 010110 010001 110101 011000 010110 1100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
100110	m
010101	V
110011	z
011010	a
010110	W
010001	R
110101	1
011000	Y
010110	W
1100	w

When combined, these characters form the encoded string: "cmVzaWR1YWw="
