About the '=' Padding

The '=' at the end of "cHJlZmVyYWJsZQ==" 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
Z	011001	25
m	100110	38
V	010101	21
y	110010	50
Y	011000	24
W	010110	22
J	001001	9
s	101100	44
Z	011001	25
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 01100110 01100101 01110010 01100001 01100010 01101100 01100101 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110000	p
01110010	r
01100101	e
01100110	f
01100101	e
01110010	r
01100001	a
01100010	b
01101100	l
01100101	e
0000

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