About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
c	01100011
o	01101111
n	01101110
f	01100110
o	01101111
r	01110010
m	01101101
a	01100001
n	01101110
c	01100011
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 111101 101110 011001 100110 111101 110010 011011 010110 000101 101110 011000 110110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
111101	9
101110	u
011001	Z
100110	m
111101	9
110010	y
011011	b
010110	W
000101	F
101110	u
011000	Y
110110	2
0101	U

When combined, these characters form the encoded string: "Y29uZm9ybWFuY2U="
