Decoding Process: bWFybGJvcm91Z2g= to marlborough

About the '=' Padding

The '=' at the end of "bWFybGJvcm91Z2g=" 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
b	011011	27
W	010110	22
F	000101	5
y	110010	50
b	011011	27
G	000110	6
J	001001	9
v	101111	47
c	011100	28
m	100110	38
9	111101	61
1	110101	53
Z	011001	25
2	110110	54
g	100000	32
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01101101 01100001 01110010 01101100 01100010 01101111 01110010 01101111 01110101 01100111 01101000 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01101101	m
01100001	a
01110010	r
01101100	l
01100010	b
01101111	o
01110010	r
01101111	o
01110101	u
01100111	g
01101000	h
00

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