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
p	01110000
o	01101111
s	01110011
t	01110100
c	01100011
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:

011100 000110 111101 110011 011101 000110 001101 100001 011100 100110 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
000110	G
111101	9
110011	z
011101	d
000110	G
001101	N
100001	h
011100	c
100110	m
0100	Q

When combined, these characters form the encoded string: "cG9zdGNhcmQ="
