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
n	01101110
t	01110100
i	01101001
b	01100010
i	01101001
o	01101111
t	01110100
i	01101001
c	01100011

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 111001 110100 011010 010110 001001 101001 011011 110111 010001 101001 011000 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
111001	5
110100	0
011010	a
010110	W
001001	J
101001	p
011011	b
110111	3
010001	R
101001	p
011000	Y
11	w

When combined, these characters form the encoded string: "YW50aWJpb3RpYw=="
