About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: Two '=' characters are added when the input length modulo 3 equals 1. This happens because the input length leaves a remainder of 1 when divided by 3, indicating that two more bytes are needed to complete the 3-byte group. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
u	01110101
n	01101110
a	01100001
n	01101110
s	01110011
w	01110111
e	01100101
r	01110010
e	01100101
d	01100100

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 111001 100001 011011 100111 001101 110111 011001 010111 001001 100101 011001 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
111001	5
100001	h
011011	b
100111	n
001101	N
110111	3
011001	Z
010111	X
001001	J
100101	l
011001	Z
00	A

When combined, these characters form the encoded string: "dW5hbnN3ZXJlZA=="
