Decoding Process: aW5zdGluY3Q= to instinct

About the '=' Padding

The '=' at the end of "aW5zdGluY3Q=" 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
a	011010	26
W	010110	22
5	111001	57
z	110011	51
d	011101	29
G	000110	6
l	100101	37
u	101110	46
Y	011000	24
3	110111	55
Q	010000	16
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01101001 01101110 01110011 01110100 01101001 01101110 01100011 01110100 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01101001	i
01101110	n
01110011	s
01110100	t
01101001	i
01101110	n
01100011	c
01110100	t
00

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