About the '=' Padding

The '=' at the end of "YWR2ZXJ0aXNlbWVudA==" 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
W	010110	22
R	010001	17
2	110110	54
Z	011001	25
X	010111	23
J	001001	9
0	110100	52
a	011010	26
X	010111	23
N	001101	13
l	100101	37
b	011011	27
W	010110	22
V	010101	21
u	101110	46
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 01100100 01110110 01100101 01110010 01110100 01101001 01110011 01100101 01101101 01100101 01101110 01110100 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100001	a
01100100	d
01110110	v
01100101	e
01110010	r
01110100	t
01101001	i
01110011	s
01100101	e
01101101	m
01100101	e
01101110	n
01110100	t
0000

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