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
f	01100110
a	01100001
m	01101101
i	01101001
l	01101100
i	01101001
a	01100001
r	01110010

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 111001 100110 011000 010110 110101 101001 011011 000110 100101 100001 011100 10

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
111001	5
100110	m
011000	Y
010110	W
110101	1
101001	p
011011	b
000110	G
100101	l
100001	h
011100	c
10	g

When combined, these characters form the encoded string: "dW5mYW1pbGlhcg=="
