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
u	01110101
n	01101110
s	01110011
u	01110101
b	01100010
s	01110011
c	01100011
r	01110010
i	01101001
b	01100010
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 111001 110011 011101 010110 001001 110011 011000 110111 001001 101001 011000 100110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
111001	5
110011	z
011101	d
010110	W
001001	J
110011	z
011000	Y
110111	3
001001	J
101001	p
011000	Y
100110	m
0101	U

When combined, these characters form the encoded string: "dW5zdWJzY3JpYmU="
