Decoding Process: YWx0ZXI= to alter

About the '=' Padding

The '=' at the end of "YWx0ZXI=" 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
x	110001	49
0	110100	52
Z	011001	25
X	010111	23
I	001000	8
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01100001 01101100 01110100 01100101 01110010 00

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100001	a
01101100	l
01110100	t
01100101	e
01110010	r
00

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