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
r	01110010
h	01101000
e	01100101
u	01110101
m	01101101
a	01100001
t	01110100
o	01101111
i	01101001
d	01100100

Step 2: Group Bits into 6-bit Chunks

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

011100 100110 100001 100101 011101 010110 110101 100001 011101 000110 111101 101001 011001 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
100110	m
100001	h
100101	l
011101	d
010110	W
110101	1
100001	h
011101	d
000110	G
111101	9
101001	p
011001	Z
00	A

When combined, these characters form the encoded string: "cmhldW1hdG9pZA=="
