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
o	01101111
w	01110111
n	01101110
w	01110111
a	01100001
r	01110010
d	01100100

Step 2: Group Bits into 6-bit Chunks

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

011001 000110 111101 110111 011011 100111 011101 100001 011100 100110 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
000110	G
111101	9
110111	3
011011	b
100111	n
011101	d
100001	h
011100	c
100110	m
0100	Q

When combined, these characters form the encoded string: "ZG93bndhcmQ="
