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
a	01100001
d	01100100
d	01100100
i	01101001
t	01110100
i	01101001
o	01101111
n	01101110
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 010001 100100 011010 010111 010001 101001 011011 110110 111001 100001 011011 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
010001	R
100100	k
011010	a
010111	X
010001	R
101001	p
011011	b
110110	2
111001	5
100001	h
011011	b
00	A

When combined, these characters form the encoded string: "YWRkaXRpb25hbA=="
