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
n	01101110
e	01100101
c	01100011
e	01100101
s	01110011
s	01110011
a	01100001
r	01110010
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 111001 101110 011001 010110 001101 100101 011100 110111 001101 100001 011100 100111 1001

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
111001	5
101110	u
011001	Z
010110	W
001101	N
100101	l
011100	c
110111	3
001101	N
100001	h
011100	c
100111	n
1001	k

When combined, these characters form the encoded string: "dW5uZWNlc3Nhcnk="
