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
b	01100010
i	01101001
b	01100010
l	01101100
i	01101001
o	01101111
g	01100111
r	01110010
a	01100001
p	01110000
h	01101000
i	01101001
c	01100011

Step 2: Group Bits into 6-bit Chunks

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

011000 100110 100101 100010 011011 000110 100101 101111 011001 110111 001001 100001 011100 000110 100001 101001 011000 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
100110	m
100101	l
100010	i
011011	b
000110	G
100101	l
101111	v
011001	Z
110111	3
001001	J
100001	h
011100	c
000110	G
100001	h
101001	p
011000	Y
11	w

When combined, these characters form the encoded string: "YmlibGlvZ3JhcGhpYw=="
