Enum BitsOfSecurity

pub enum BitsOfSecurity {
    AES80,

    AES128,
    AES192,
    AES256,
    Custom {

    },

}

The number of bits of security as compared to the AES cryptosystem. Check https://www.keylength.com/en/4/ for recommendations.

Variants

AES80

Security that is equivalent to the security of the 2TDEA cryptosystem. This choice of parameters is not secure and is only used for legacy.

AES112

This level of security is expected to be safe until 2030.

AES128

Security that is equivalent to that of 128 bits in the AES cryptosystem. This level of security is expected to be safe until 2030 & beyond.

AES192

Security that is equivalent to that of 192 bits in the AES cryptosystem. This level of security is expected to be safe until 2030 & beyond.

AES256

Security that is equivalent to that of 256 bits in the AES cryptosystem. This level of security is expected to be safe until 2030 & beyond.

Custom

Security that is equivalent to a number of bits pk_bits in accordance to the size of a public key modulus. Note that any number lower than 1024 is considered extremely insecure.

Fields

pk_bits: u32

The number of bits in a public key (factoring) modulus.

ToyParameters

Completely insecure parameters that are only useful for testing due to their speed.

Implementations

impl BitsOfSecurity

pub fn to_public_key_bit_length(&self) -> u32

Returns the required modulus size for a given symmetric security level in the asymmetric setting.

Trait Implementations

impl Default for BitsOfSecurity

fn default() -> Self

Returns the “default value” for a type.
