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
r	01110010
a	01100001
c	01100011
t	01110100
i	01101001
c	01100011
a	01100001
l	01101100
l	01101100
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011100 000111 001001 100001 011000 110111 010001 101001 011000 110110 000101 101100 011011 000111 1001

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
000111	H
001001	J
100001	h
011000	Y
110111	3
010001	R
101001	p
011000	Y
110110	2
000101	F
101100	s
011011	b
000111	H
1001	k

When combined, these characters form the encoded string: "cHJhY3RpY2FsbHk="
