Decoding Process: aGVsaWNvcHRlcg== to helicopter

About the '=' Padding

The '=' at the end of "aGVsaWNvcHRlcg==" 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
G	000110	6
V	010101	21
s	101100	44
a	011010	26
W	010110	22
N	001101	13
v	101111	47
c	011100	28
H	000111	7
R	010001	17
l	100101	37
c	011100	28
g	100000	32
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01101000 01100101 01101100 01101001 01100011 01101111 01110000 01110100 01100101 01110010 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01101000	h
01100101	e
01101100	l
01101001	i
01100011	c
01101111	o
01110000	p
01110100	t
01100101	e
01110010	r
0000

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