About the '=' Padding

The '=' at the end of "a2V5d29yZA==" 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
2	110110	54
V	010101	21
5	111001	57
d	011101	29
2	110110	54
9	111101	61
y	110010	50
Z	011001	25
A	000000	0
=	padding (000000)	-
=	padding (000000)	-

Step 2: Group Bits into Bytes

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

01101011 01100101 01111001 01110111 01101111 01110010 01100100 0000

Step 3: Convert Binary to ASCII

Binary Value	ASCII Character
01101011	k
01100101	e
01111001	y
01110111	w
01101111	o
01110010	r
01100100	d
0000

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