Decoding Process: cG9zaXg= to posix

About the '=' Padding

The '=' at the end of "cG9zaXg=" 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
G	000110	6
9	111101	61
z	110011	51
a	011010	26
X	010111	23
g	100000	32
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01110000 01101111 01110011 01101001 01111000 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110000	p
01101111	o
01110011	s
01101001	i
01111000	x
00

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