Decoding Process: cnA= to rp

About the '=' Padding

The '=' at the end of "cnA=" 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
n	100111	39
A	000000	0
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01110010 01110000 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110010	r
01110000	p
00

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