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
p	01110000
o	01101111
s	01110011
t	01110100
g	01100111
r	01110010
e	01100101
s	01110011
q	01110001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011100 000110 111101 110011 011101 000110 011101 110010 011001 010111 001101 110001 011011 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
000110	G
111101	9
110011	z
011101	d
000110	G
011101	d
110010	y
011001	Z
010111	X
001101	N
110001	x
011011	b
00	A

When combined, these characters form the encoded string: "cG9zdGdyZXNxbA=="
