Decoding Process: ZG93bnN0cmVhbQ== to downstream

About the '=' Padding

The '=' at the end of "ZG93bnN0cmVhbQ==" 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
Z	011001	25
G	000110	6
9	111101	61
3	110111	55
b	011011	27
n	100111	39
N	001101	13
0	110100	52
c	011100	28
m	100110	38
V	010101	21
h	100001	33
b	011011	27
Q	010000	16
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01100100 01101111 01110111 01101110 01110011 01110100 01110010 01100101 01100001 01101101 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01100100	d
01101111	o
01110111	w
01101110	n
01110011	s
01110100	t
01110010	r
01100101	e
01100001	a
01101101	m
0000

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