Decoding Process: cm9vZg== to roof

About the '=' Padding

The '=' at the end of "cm9vZg==" 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
Z	011001	25
g	100000	32
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01110010 01101111 01101111 01100110 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110010	r
01101111	o
01101111	o
01100110	f
0000

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