Decoding Process: cHJvcG9zaXRpb24= to proposition

About the '=' Padding

The '=' at the end of "cHJvcG9zaXRpb24=" 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
v	101111	47
c	011100	28
G	000110	6
9	111101	61
z	110011	51
a	011010	26
X	010111	23
R	010001	17
p	101001	41
b	011011	27
2	110110	54
4	111000	56
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01110000 01110010 01101111 01110000 01101111 01110011 01101001 01110100 01101001 01101111 01101110 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01110000	p
01110010	r
01101111	o
01110000	p
01101111	o
01110011	s
01101001	i
01110100	t
01101001	i
01101111	o
01101110	n
00

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