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
u	01110101
d	01100100
i	01101001
o	01101111
b	01100010
o	01101111
o	01101111
k	01101011
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011000 010111 010101 100100 011010 010110 111101 100010 011011 110110 111101 101011 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010111	X
010101	V
100100	k
011010	a
010110	W
111101	9
100010	i
011011	b
110110	2
111101	9
101011	r
011100	c
11	w

When combined, these characters form the encoded string: "YXVkaW9ib29rcw=="
