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
p	01110000
r	01110010
o	01101111
t	01110100
o	01101111
t	01110100
y	01111001
p	01110000
e	01100101
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011100 000111 001001 101111 011101 000110 111101 110100 011110 010111 000001 100101 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
000111	H
001001	J
101111	v
011101	d
000110	G
111101	9
110100	0
011110	e
010111	X
000001	B
100101	l
011100	c
11	w

When combined, these characters form the encoded string: "cHJvdG90eXBlcw=="
