Decoding Process: cHJlbGltaW5hcnk= to preliminary

About the '=' Padding

The '=' at the end of "cHJlbGltaW5hcnk=" 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
H	000111	7
J	001001	9
l	100101	37
b	011011	27
G	000110	6
l	100101	37
t	101101	45
a	011010	26
W	010110	22
5	111001	57
h	100001	33
c	011100	28
n	100111	39
k	100100	36
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01110000 01110010 01100101 01101100 01101001 01101101 01101001 01101110 01100001 01110010 01111001 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110000	p
01110010	r
01100101	e
01101100	l
01101001	i
01101101	m
01101001	i
01101110	n
01100001	a
01110010	r
01111001	y
00

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