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
i	01101001
l	01101100
h	01101000
o	01101111
u	01110101
e	01100101
t	01110100
t	01110100
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011100 110110 100101 101100 011010 000110 111101 110101 011001 010111 010001 110100 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110110	2
100101	l
101100	s
011010	a
000110	G
111101	9
110101	1
011001	Z
010111	X
010001	R
110100	0
011001	Z
01	Q

When combined, these characters form the encoded string: "c2lsaG91ZXR0ZQ=="
