Destroy a Secure Buffer key safely
A piece in the puzzle towards secure-key-management
var destroyKey = require('secure-destroy-key')
destroyKey(key)- Once the key is destroyed, any access to it (whether read or write) will crash your program with no mercy
secureBuf must be a Secure Buffer created with sodium-native@2.4 or greater.
It can also be a primitive object with some of the following properties (eg.
in case of a key pair): private, secret, privateKey, secretKey,
public, publicKey, identity or identityKey, which in turn will be called
with destroyKey
Destroying the secureBuf will safely wipe the key from memory and mark it for
noaccess, to prevent any accidental misuse.
Note that the secureBuf looks like a normal Buffer, but has some extra
properties. You can read more about

Be wary about using any of the default Buffer operations on this Secure Buffer.
