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
s	01110011
e	01100101
r	01110010
n	01101110
a	01100001
m	01101101
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011101 010111 001101 100101 011100 100110 111001 100001 011011 010110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010111	X
001101	N
100101	l
011100	c
100110	m
111001	5
100001	h
011011	b
010110	W
0101	U

When combined, these characters form the encoded string: "dXNlcm5hbWU="
