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
i	01101001
m	01101101
p	01110000
o	01101111
s	01110011
s	01110011
i	01101001
b	01100010
l	01101100
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011010 010110 110101 110000 011011 110111 001101 110011 011010 010110 001001 101100 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010110	W
110101	1
110000	w
011011	b
110111	3
001101	N
110011	z
011010	a
010110	W
001001	J
101100	s
011001	Z
01	Q

When combined, these characters form the encoded string: "aW1wb3NzaWJsZQ=="
