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
b	01100010
s	01110011
i	01101001
d	01100100
i	01101001
a	01100001
r	01110010
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 010101 100010 011100 110110 100101 100100 011010 010110 000101 110010 011110 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110111	3
010101	V
100010	i
011100	c
110110	2
100101	l
100100	k
011010	a
010110	W
000101	F
110010	y
011110	e
01	Q

When combined, these characters form the encoded string: "c3Vic2lkaWFyeQ=="
