Trait Zeroize 

pub trait Zeroize {
    // Required method
    fn zeroize(&mut self);
}

Trait for securely erasing values from memory.

Required Methods

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Zeroize for SecretKey

fn zeroize(&mut self)

Securely clears the shared secret from memory.

Security

This implementation follows the same security methodology as the zeroize crate to ensure that sensitive cryptographic material is reliably cleared from memory:

• Volatile writes: Uses ptr::write_volatile to prevent dead store elimination and other compiler optimizations that might remove the zeroing operation.
• Memory ordering: Includes a sequentially consistent compiler fence (SeqCst) to prevent instruction reordering that could expose the secret data after this function returns.

impl<Z> Zeroize for Option<Z>

where Z: Zeroize,

fn zeroize(&mut self)

impl<Z> Zeroize for [Z]

where Z: DefaultIsZeroes,

Impl Zeroize on slices of types that can be zeroized with Default.

This impl can eventually be optimized using an memset intrinsic, such as core::intrinsics::volatile_set_memory. For that reason the blanket impl on slices is bounded by DefaultIsZeroes.

To zeroize a mut slice of Z: Zeroize which does not impl DefaultIsZeroes, call iter_mut().zeroize().

fn zeroize(&mut self)

impl<Z> Zeroize for Box<[Z]>

where Z: Zeroize,

Available on crate feature alloc only.

fn zeroize(&mut self)

Unlike Vec, Box<[Z]> cannot reallocate, so we can be sure that we are not leaving values on the heap.

impl<Z> Zeroize for Vec<Z>

where Z: Zeroize,

Available on crate feature alloc only.

fn zeroize(&mut self)

“Best effort” zeroization for Vec.

Ensures the entire capacity of the Vec is zeroed. Cannot ensure that previous reallocations did not leave values on the heap.

impl<Z> Zeroize for PhantomData<Z>

PhantomData is always zero sized so provide a Zeroize implementation.

impl<Z> Zeroize for IterMut<'_, Z>

where Z: Zeroize,

impl<Z> Zeroize for MaybeUninit<Z>

Impl Zeroize on MaybeUninit types.

This fills the memory with zeroes. Note that this ignore invariants that Z might have, because MaybeUninit removes all invariants.

fn zeroize(&mut self)

impl<Z> Zeroize for [MaybeUninit<Z>]

Impl Zeroize on slices of MaybeUninit types.

This impl can eventually be optimized using an memset intrinsic, such as core::intrinsics::volatile_set_memory.

This fills the slice with zeroes.

Note that this ignore invariants that Z might have, because MaybeUninit removes all invariants.

Available on crate feature zeroize only.

NOTE: this does not zeroize the parameters, in order to maintain some form of type consistency
