Module constant_time 

Constant-time operations to prevent timing attacks.

These small primitives are owned by dcrypt so the published implementation does not need an unsafe-containing dependency for masks and comparisons.

Structs

Choice

A one-bit value used by constant-time operations.

CtOption

An option whose validity is represented by a Choice.

Traits

ConditionallySelectable

Select between two values without branching on choice.

ConstantTimeEq

Compare two values without data-dependent early exit.

Functions

ct_eq

Constant-time comparison of two byte slices
