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
a	01100001
d	01100100
i	01101001
c	01100011
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011100 100110 000101 100100 011010 010110 001101 100001 011011 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
100110	m
000101	F
100100	k
011010	a
010110	W
001101	N
100001	h
011011	b
00	A

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