Consider the following two statements:
- A Hash function, which is used for computing digital signatures, is an injective function
- An encryption technique such as $\text{DES}$ performs a permutation on the elements of its input alphabet
-
Both are false
-
$\text{(I)}$ is true $\text{(II)}$ is false
-
$\text{(II)}$ is true $\text{(I)}$ is false
-
Both are true
