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
f	01100110
o	01101111
r	01110010
e	01100101
i	01101001
g	01100111
n	01101110
e	01100101
r	01110010
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011001 100110 111101 110010 011001 010110 100101 100111 011011 100110 010101 110010 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
100110	m
111101	9
110010	y
011001	Z
010110	W
100101	l
100111	n
011011	b
100110	m
010101	V
110010	y
011100	c
11	w

When combined, these characters form the encoded string: "Zm9yZWlnbmVycw=="
