Decoding Process: aW1wb3J0YW50bHk= to importantly

About the '=' Padding

The '=' at the end of "aW1wb3J0YW50bHk=" 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
a	011010	26
W	010110	22
1	110101	53
w	110000	48
b	011011	27
3	110111	55
J	001001	9
0	110100	52
Y	011000	24
W	010110	22
5	111001	57
0	110100	52
b	011011	27
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):

01101001 01101101 01110000 01101111 01110010 01110100 01100001 01101110 01110100 01101100 01111001 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01101001	i
01101101	m
01110000	p
01101111	o
01110010	r
01110100	t
01100001	a
01101110	n
01110100	t
01101100	l
01111001	y
00

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