- Method Detail
  - getPublicKey
```
PublicKey getPublicKey(KeyMetadata keyMetadata)
```
    Accessor for the public-key corresponding to the supplied key meta-data. This method exists to support implementations that hold private-key material internally, yet need a way for external callers to determine the actual public key for signature verification or other purposes.
    
    Parameters:
    
    keyMetadata - A KeyMetadata for a key-pair.
    
    Returns:
    
    A PublicKey.
  - keyStoreType
```
KeyStoreType keyStoreType()
```
    The type of org.xrpl4j.crypto.keystore this signer can be used with.
    
    Returns:
    
    A KeyStoreType.
