Decoding Process: ZW50cm9weQ== to entropy

About the '=' Padding

The '=' at the end of "ZW50cm9weQ==" 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
Z	011001	25
W	010110	22
5	111001	57
0	110100	52
c	011100	28
m	100110	38
9	111101	61
w	110000	48
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):

01100101 01101110 01110100 01110010 01101111 01110000 01111001 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100101	e
01101110	n
01110100	t
01110010	r
01101111	o
01110000	p
01111001	y
0000

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