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
s	01110011
u	01110101
r	01110010
p	01110000
r	01110010
i	01101001
s	01110011
i	01101001
n	01101110
g	01100111

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 010101 110010 011100 000111 001001 101001 011100 110110 100101 101110 011001 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110111	3
010101	V
110010	y
011100	c
000111	H
001001	J
101001	p
011100	c
110110	2
100101	l
101110	u
011001	Z
11	w

When combined, these characters form the encoded string: "c3VycHJpc2luZw=="
