Decoding Process: Y3RybA== to ctrl

About the '=' Padding

The '=' at the end of "Y3RybA==" 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
Y	011000	24
3	110111	55
R	010001	17
y	110010	50
b	011011	27
A	000000	0
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01100011 01110100 01110010 01101100 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100011	c
01110100	t
01110010	r
01101100	l
0000

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