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
s	01110011
e	01100101
f	01100110
u	01110101
l	01101100
n	01101110
e	01100101
s	01110011
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011101 010111 001101 100101 011001 100111 010101 101100 011011 100110 010101 110011 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010111	X
001101	N
100101	l
011001	Z
100111	n
010101	V
101100	s
011011	b
100110	m
010101	V
110011	z
011100	c
11	w

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