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
d	01100100
i	01101001
f	01100110
f	01100110
i	01101001
c	01100011
u	01110101
l	01101100
t	01110100
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011001 000110 100101 100110 011001 100110 100101 100011 011101 010110 110001 110100 011110 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
000110	G
100101	l
100110	m
011001	Z
100110	m
100101	l
100011	j
011101	d
010110	W
110001	x
110100	0
011110	e
01	Q

When combined, these characters form the encoded string: "ZGlmZmljdWx0eQ=="
