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
c	01100011
r	01110010
i	01101001
t	01110100
i	01101001
c	01100011
a	01100001
l	01101100
l	01101100
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011000 110111 001001 101001 011101 000110 100101 100011 011000 010110 110001 101100 011110 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110111	3
001001	J
101001	p
011101	d
000110	G
100101	l
100011	j
011000	Y
010110	W
110001	x
101100	s
011110	e
01	Q

When combined, these characters form the encoded string: "Y3JpdGljYWxseQ=="
