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
g	01100111
a	01100001
s	01110011
t	01110100
r	01110010
o	01101111
i	01101001
n	01101110
t	01110100
e	01100101
s	01110011
t	01110100
i	01101001
n	01101110
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011001 110110 000101 110011 011101 000111 001001 101111 011010 010110 111001 110100 011001 010111 001101 110100 011010 010110 111001 100001 011011 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
110110	2
000101	F
110011	z
011101	d
000111	H
001001	J
101111	v
011010	a
010110	W
111001	5
110100	0
011001	Z
010111	X
001101	N
110100	0
011010	a
010110	W
111001	5
100001	h
011011	b
00	A

When combined, these characters form the encoded string: "Z2FzdHJvaW50ZXN0aW5hbA=="
