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
e	01100101
m	01101101
o	01101111
r	01110010
a	01100001
n	01101110
d	01100100
u	01110101
m	01101101

Step 2: Group Bits into 6-bit Chunks

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

011011 010110 010101 101101 011011 110111 001001 100001 011011 100110 010001 110101 011011 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
010110	W
010101	V
101101	t
011011	b
110111	3
001001	J
100001	h
011011	b
100110	m
010001	R
110101	1
011011	b
01	Q

When combined, these characters form the encoded string: "bWVtb3JhbmR1bQ=="
