Decoding Process: YXR0bg== to attn

About the '=' Padding

The '=' at the end of "YXR0bg==" 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
X	010111	23
R	010001	17
0	110100	52
b	011011	27
g	100000	32
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01100001 01110100 01110100 01101110 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100001	a
01110100	t
01110100	t
01101110	n
0000

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