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
s	01110011
t	01110100
r	01110010
u	01110101
c	01100011
t	01110100
o	01101111
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 110011 011101 000111 001001 110101 011000 110111 010001 101111 011100 10

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010110	W
111001	5
110011	z
011101	d
000111	H
001001	J
110101	1
011000	Y
110111	3
010001	R
101111	v
011100	c
10	g

When combined, these characters form the encoded string: "aW5zdHJ1Y3Rvcg=="
