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
s	01110011
m	01101101
a	01100001
r	01110010
t	01110100
p	01110000
h	01101000
o	01101111
n	01101110
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011100 110110 110101 100001 011100 100111 010001 110000 011010 000110 111101 101110 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110110	2
110101	1
100001	h
011100	c
100111	n
010001	R
110000	w
011010	a
000110	G
111101	9
101110	u
011001	Z
01	Q

When combined, these characters form the encoded string: "c21hcnRwaG9uZQ=="
