Trait dup_crypto::keys::PrivateKey

pub trait PrivateKey: Clone + Display + Debug + PartialEq + Eq + ToBase58 {
    type Signature: Signature;
    fn from_base58(base58_string: &str) -> Result<Self, BaseConvertionError>;
    fn sign(&self, message: &[u8]) -> Self::Signature;
}

Define the operations that can be performed on a cryptographic private key.

A PrivateKey can be converted from/to Base58 format. When converted back and forth the value should be the same.

A PrivateKey is used to sign a message. The corresponding PublicKey will then be used to verify that signature.

Associated Types

Required methods

fn from_base58(base58_string: &str) -> Result<Self, BaseConvertionError>

Create a PrivateKey from a Base58 string.

The Base58 string should contains only valid Base58 characters and have a correct length. If it's not the case, a BaseConvertionError is returned with the corresponding variant.

fn sign(&self, message: &[u8]) -> Self::Signature

Sign a message with this private key.
