Decoding Process: YW50aWJvZHk= to antibody

About the '=' Padding

The '=' at the end of "YW50aWJvZHk=" 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
5	111001	57
0	110100	52
a	011010	26
W	010110	22
J	001001	9
v	101111	47
Z	011001	25
H	000111	7
k	100100	36
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01100001 01101110 01110100 01101001 01100010 01101111 01100100 01111001 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100001	a
01101110	n
01110100	t
01101001	i
01100010	b
01101111	o
01100100	d
01111001	y
00

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