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
d	01100100
o	01101111
w	01110111
n	01101110
s	01110011
t	01110100
a	01100001
i	01101001
r	01110010
s	01110011

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 001101 110100 011000 010110 100101 110010 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
000110	G
111101	9
110111	3
011011	b
100111	n
001101	N
110100	0
011000	Y
010110	W
100101	l
110010	y
011100	c
11	w

When combined, these characters form the encoded string: "ZG93bnN0YWlycw=="
