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
u	01110101
l	01101100
t	01110100
r	01110010
a	01100001
s	01110011
o	01101111
n	01101110
i	01101001
c	01100011

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 110001 110100 011100 100110 000101 110011 011011 110110 111001 101001 011000 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
110001	x
110100	0
011100	c
100110	m
000101	F
110011	z
011011	b
110110	2
111001	5
101001	p
011000	Y
11	w

When combined, these characters form the encoded string: "dWx0cmFzb25pYw=="
