Decoding Process: aW1wb3NzaWJsZQ== to impossible

About the '=' Padding

The '=' at the end of "aW1wb3NzaWJsZQ==" 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
a	011010	26
W	010110	22
1	110101	53
w	110000	48
b	011011	27
3	110111	55
N	001101	13
z	110011	51
a	011010	26
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):

01101001 01101101 01110000 01101111 01110011 01110011 01101001 01100010 01101100 01100101 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01101001	i
01101101	m
01110000	p
01101111	o
01110011	s
01110011	s
01101001	i
01100010	b
01101100	l
01100101	e
0000

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