Struct Config 

#[non_exhaustive]
pub struct Config { /* private fields */ }

RSA accelerator configuration.

The default is the most secure: constant time on and search acceleration off. The ESP32 has neither option, so its Config is empty.

Implementations

impl Config

pub fn with_constant_time(self, constant_time: bool) -> Self

Assign the given value to the constant_time field.

pub fn constant_time(&self) -> bool

Constant time operation for modular exponentiation.

Turning it off makes modular exponentiation faster for an exponent with many 0 bits, and exposes the exponent to timing-based side-channel attacks. Turn it off only for a public exponent, such as when verifying a signature.

Default value: true.

pub fn with_search_acceleration(self, search_acceleration: bool) -> Self

Assign the given value to the search_acceleration field.

pub fn search_acceleration(&self) -> bool

Search acceleration for modular exponentiation.

Turning it on makes modular exponentiation faster by skipping the exponent’s bits above its most significant set bit, and exposes the exponent’s length. Turn it on only for a public exponent, such as when verifying a signature.

Default value: false.
