This seems reasonable to me, though the memory safety concern is likely less
a problem with rust
You can probably make something like this:
```rust
struct SecureKey {
inner: Vec<u8>
}
impl Drop for SecureKey {
...
// reset memory here
}
/// allow Secure key to be coerced to &[u8]
impl AsRef<[u8]> for SecureKey {
fn as_ref(&self) -> &[u8] {
&inner
}
}
```
