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
d	01100100
e	01100101
m	01101101
o	01101111
n	01101110
s	01110011
t	01110100
r	01110010
a	01100001
t	01110100
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011001 000110 010101 101101 011011 110110 111001 110011 011101 000111 001001 100001 011101 000110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
000110	G
010101	V
101101	t
011011	b
110110	2
111001	5
110011	z
011101	d
000111	H
001001	J
100001	h
011101	d
000110	G
0101	U

When combined, these characters form the encoded string: "ZGVtb25zdHJhdGU="
