Decoding Process: aGVpZGVsYmVyZw== to heidelberg

About the '=' Padding

The '=' at the end of "aGVpZGVsYmVyZw==" 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
G	000110	6
V	010101	21
p	101001	41
Z	011001	25
G	000110	6
V	010101	21
s	101100	44
Y	011000	24
m	100110	38
V	010101	21
y	110010	50
Z	011001	25
w	110000	48
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01101000 01100101 01101001 01100100 01100101 01101100 01100010 01100101 01110010 01100111 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01101000	h
01100101	e
01101001	i
01100100	d
01100101	e
01101100	l
01100010	b
01100101	e
01110010	r
01100111	g
0000

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