Expand description

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

A PublicKey can be converted from/to Base64 format. When converted back and forth the value should be the same.

A PublicKey is used to verify the signature of a message with the associated PrivateKey.

Required Associated Types§

Source

type Signature: Signature

Signature type of associated cryptosystem.

Required Methods§

Source

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

Create a PublicKey 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.

Source

fn to_bytes_vector(&self) -> Vec<u8> ⓘ

Convert into bytes vector

Source

fn verify( &self, message: &[u8], signature: &Self::Signature, ) -> Result<(), SigError>

Verify a signature with this public key.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
