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
m	01101101
u	01110101
l	01101100
t	01110100
i	01101001
m	01101101
e	01100101
d	01100100
i	01101001
a	01100001

Step 2: Group Bits into 6-bit Chunks

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

011011 010111 010101 101100 011101 000110 100101 101101 011001 010110 010001 101001 011000 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
010111	X
010101	V
101100	s
011101	d
000110	G
100101	l
101101	t
011001	Z
010110	W
010001	R
101001	p
011000	Y
01	Q

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