Decoding Process: cm9vbW1hdGU= to roommate

About the '=' Padding

The '=' at the end of "cm9vbW1hdGU=" 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
m	100110	38
9	111101	61
v	101111	47
b	011011	27
W	010110	22
1	110101	53
h	100001	33
d	011101	29
G	000110	6
U	010100	20
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01110010 01101111 01101111 01101101 01101101 01100001 01110100 01100101 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110010	r
01101111	o
01101111	o
01101101	m
01101101	m
01100001	a
01110100	t
01100101	e
00

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