=== Code examples

==== Noncompliant code example

[source,go,diff-id=1,diff-type=noncompliant]
----
import "math/rand"

a := make([]byte, 10)
rand.Read(a) // Sensitive
----

[source,go,diff-id=2,diff-type=noncompliant]
----
import "math/rand"

num := rand.Intn(100) // Sensitive
----

==== Compliant solution

[source,go,diff-id=1,diff-type=compliant]
----
import "crypto/rand"

a := make([]byte, 10)
_, err := rand.Read(a)
if err != nil {
    panic(err)
}
----

[source,go,diff-id=2,diff-type=compliant]
----
import "crypto/rand"

temp, err := rand.Int(rand.Reader, big.NewInt(100))
if err != nil {
    panic(err)
}
num := temp.Int64()
----
