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
p	01110000
r	01110010
e	01100101
d	01100100
i	01101001
c	01100011
t	01110100
a	01100001
b	01100010
l	01101100
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 110000 011100 100110 010101 100100 011010 010110 001101 110100 011000 010110 001001 101100 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
111001	5
110000	w
011100	c
100110	m
010101	V
100100	k
011010	a
010110	W
001101	N
110100	0
011000	Y
010110	W
001001	J
101100	s
011001	Z
01	Q

When combined, these characters form the encoded string: "dW5wcmVkaWN0YWJsZQ=="
