Trait PrivateKeyDataProvider 

pub trait PrivateKeyDataProvider {
    // Required method
    fn private_key_data(&self) -> Vec<u8> ;
}

A trait for types that can provide unique data for cryptographic key derivation.

Types implementing PrivateKeyDataProvider can be used as seed material for cryptographic key derivation. The provided data should be sufficiently random and unpredictable to ensure the security of the derived keys.

This trait is particularly useful for:

• Deterministic key generation systems
• Key recovery mechanisms
• Key derivation hierarchies
• Hierarchical deterministic wallet implementations

Security Considerations

Implementers of this trait should ensure that:

• The data they provide has sufficient entropy
• The data is properly protected in memory
• Any serialization or storage is done securely
• Appropriate zeroization occurs when data is no longer needed

Required Methods

fn private_key_data(&self) -> Vec<u8>

Returns unique data from which cryptographic keys can be derived.

The returned data should be sufficiently random and have enough entropy to serve as the basis for secure cryptographic key derivation.

Returns

A vector of bytes containing the private key data.

Implementations on Foreign Types

impl PrivateKeyDataProvider for dyn AsRef<[u8]>

Implementation of PrivateKeyDataProvider for any type that can be referenced as a byte slice.

This allows any type that implements AsRef<[u8]> to be used as a source of private key data.

fn private_key_data(&self) -> Vec<u8>

Implementors

impl PrivateKeyDataProvider for Seed

Implements PrivateKeyDataProvider to use seed data for key derivation.
