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
l	01101100
i	01101001
g	01100111
h	01101000
t	01110100
h	01101000
o	01101111
u	01110101
s	01110011
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011011 000110 100101 100111 011010 000111 010001 101000 011011 110111 010101 110011 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
000110	G
100101	l
100111	n
011010	a
000111	H
010001	R
101000	o
011011	b
110111	3
010101	V
110011	z
011001	Z
01	Q

When combined, these characters form the encoded string: "bGlnaHRob3VzZQ=="
