Decoding Process: YXNzdA== to asst

About the '=' Padding

The '=' at the end of "YXNzdA==" 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
X	010111	23
N	001101	13
z	110011	51
d	011101	29
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):

01100001 01110011 01110011 01110100 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100001	a
01110011	s
01110011	s
01110100	t
0000

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