Decoding Process: Y29uc3RyYWludA== to constraint

About the '=' Padding

The '=' at the end of "Y29uc3RyYWludA==" 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
2	110110	54
9	111101	61
u	101110	46
c	011100	28
3	110111	55
R	010001	17
y	110010	50
Y	011000	24
W	010110	22
l	100101	37
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):

01100011 01101111 01101110 01110011 01110100 01110010 01100001 01101001 01101110 01110100 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100011	c
01101111	o
01101110	n
01110011	s
01110100	t
01110010	r
01100001	a
01101001	i
01101110	n
01110100	t
0000

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