Implementors

impl<S: Sponge + Default> PrivateKeyGenerator for WotsShakePrivateKeyGenerator<S>[src]

This is supported on crate feature wots_deprecated_do_not_use only.

type PrivateKey = WotsPrivateKey<S>

type Error = Error

fn generate_from_entropy(
    &self,
    entropy: &Trits<T1B1>
) -> Result<Self::PrivateKey, Self::Error>[src]

Derives a private key from entropy using the SHAKE256 extendable-output function. The entropy must be a slice of exactly 243 trits where the last trit is zero. Derives its security assumptions from the properties of the underlying SHAKE function.

impl<S: Sponge + Default> PrivateKeyGenerator for WotsSpongePrivateKeyGenerator<S>[src]

This is supported on crate feature wots_deprecated_do_not_use only.

type PrivateKey = WotsPrivateKey<S>

type Error = Error

fn generate_from_entropy(
    &self,
    entropy: &Trits<T1B1>
) -> Result<Self::PrivateKey, Self::Error>[src]

Derives a private key from entropy using the provided ternary sponge construction. The entropy must be a slice of exactly 243 trits where the last trit is zero. Deprecated: only generates secure keys for sponge constructions, but Kerl is not a true sponge construction. Consider using shake instead or sponge with Curl. In case that Kerl must be used in sponge, it must be assured that no chunk of the private key is ever revealed, as this would allow the reconstruction of successive chunks (also known as “M-bug”). Provides compatibility to the currently used key derivation.
