Struct SecureBox 

pub struct SecureBox<T>
where
    T: Copy,
{ /* private fields */ }

A data type suitable for storing sensitive information such as passwords and private keys in memory, that implements:

• Automatic zeroing in Drop
• Constant time comparison in PartialEq (does not short circuit on the first different character; but terminates instantly if strings have different length)
• Outputting ***SECRET*** to prevent leaking secrets into logs in fmt::Debug and fmt::Display
• Automatic mlock to protect against leaking into swap (any unix)
• Automatic madvise(MADV_NOCORE/MADV_DONTDUMP) to protect against leaking into core dumps (FreeBSD, DragonflyBSD, Linux)

Implementations

impl<T> SecureBox<T>

where T: Copy,

pub fn new(cont: Box<T>) -> Self

pub fn unsecure(&self) -> &T

Borrow the contents of the string.

Panics

Panics if the content has already been dropped.

pub fn unsecure_mut(&mut self) -> &mut T

Mutably borrow the contents of the string.

Panics

Panics if the content has already been dropped.

Trait Implementations

impl<T> Borrow<T> for SecureBox<T>

where T: Copy,

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T> BorrowMut<T> for SecureBox<T>

where T: Copy,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value.

impl<T: Copy> Clone for SecureBox<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Copy + ConstantTimeEq> ConstantTimeEq for SecureBox<T>

fn ct_eq(&self, other: &Self) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl<T> Debug for SecureBox<T>

where T: Copy,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Display for SecureBox<T>

where T: Copy,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Drop for SecureBox<T>

where T: Copy,

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<T, U> Index<U> for SecureBox<T>

where T: Index<U> + Copy,

type Output = <T as Index<U>>::Output

The returned type after indexing.

fn index(&self, index: U) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<T: Copy + ConstantTimeEq> PartialEq for SecureBox<T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
