Decoding Process: c3BlY2ltZW4= to specimen

About the '=' Padding

The '=' at the end of "c3BlY2ltZW4=" 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
c	011100	28
3	110111	55
B	000001	1
l	100101	37
Y	011000	24
2	110110	54
l	100101	37
t	101101	45
Z	011001	25
W	010110	22
4	111000	56
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01110011 01110000 01100101 01100011 01101001 01101101 01100101 01101110 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110011	s
01110000	p
01100101	e
01100011	c
01101001	i
01101101	m
01100101	e
01101110	n
00

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