About the '=' Padding

The '=' at the end of "Y29uZmlybXM=" 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
2	110110	54
9	111101	61
u	101110	46
Z	011001	25
m	100110	38
l	100101	37
y	110010	50
b	011011	27
X	010111	23
M	001100	12
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01100011 01101111 01101110 01100110 01101001 01110010 01101101 01110011 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100011	c
01101111	o
01101110	n
01100110	f
01101001	i
01110010	r
01101101	m
01110011	s
00

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