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
e	01100101
c	01100011
o	01101111
n	01101110
o	01101111
m	01101101
i	01101001
c	01100011
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011001 010110 001101 101111 011011 100110 111101 101101 011010 010110 001101 100001 011011 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
010110	W
001101	N
101111	v
011011	b
100110	m
111101	9
101101	t
011010	a
010110	W
001101	N
100001	h
011011	b
00	A

When combined, these characters form the encoded string: "ZWNvbm9taWNhbA=="
