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
i	01101001
n	01101110
t	01110100
r	01110010
a	01100001
c	01100011
e	01100101
l	01101100
l	01101100
u	01110101
l	01101100
a	01100001
r	01110010

Step 2: Group Bits into 6-bit Chunks

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

011010 010110 111001 110100 011100 100110 000101 100011 011001 010110 110001 101100 011101 010110 110001 100001 011100 10

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010110	W
111001	5
110100	0
011100	c
100110	m
000101	F
100011	j
011001	Z
010110	W
110001	x
101100	s
011101	d
010110	W
110001	x
100001	h
011100	c
10	g

When combined, these characters form the encoded string: "aW50cmFjZWxsdWxhcg=="
