About the '=' Padding

The '=' at the end of "cHJlc3VtYWJseQ==" is padding. Base64 encoding requires the input length to be divisible by 4. When it's not, '=' characters are added as padding. These padding characters are represented as '000000' in binary but are not used in the final decoded output.

Step 1: Map Base64 Characters to Binary

Base64 Character	Binary Value	Decimal Value
c	011100	28
H	000111	7
J	001001	9
l	100101	37
c	011100	28
3	110111	55
V	010101	21
t	101101	45
Y	011000	24
W	010110	22
J	001001	9
s	101100	44
e	011110	30
Q	010000	16
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

The binary string is grouped into 8-bit chunks (1 byte each):

01110000 01110010 01100101 01110011 01110101 01101101 01100001 01100010 01101100 01111001 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110000	p
01110010	r
01100101	e
01110011	s
01110101	u
01101101	m
01100001	a
01100010	b
01101100	l
01111001	y
0000

When combined, these characters form the decoded string: "presumably"
