PublicKeySource (com.zerodeplibs:zerodep-web-push-java 2.1.2 API)

```
public interface PublicKeySource
```
Implementations of this interface represent a source of an ECPublicKey.

A PublicKeySource validates the extracted public key depending on its implementation.

Typically, to create a PublicKeySource, a factory method defined in PublicKeySources is used.

Thread Safety:

Depends on implementations. Typically, an implementation of this interface is not thread-safe.

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`ECPublicKey`	`extract()`	Extracts the `ECPublicKey` from the source represented by this object.

  - extract
```
ECPublicKey extract()
```
    Extracts the ECPublicKey from the source represented by this object.
    
    Returns:
    
    the elliptic curve (EC) public key.
    
    Throws:
    
    InvalidECPublicKeyException - if the extracted public key is invalid(Depending on the implementation).
  - extractBytesInUncompressedForm
```
byte[] extractBytesInUncompressedForm()
```
    Extracts the octet sequence of the elliptic curve (EC) public key in uncompressed form.
    
    Returns:
    
    the octet sequence of the public key in uncompressed form.
    
    Throws:
    
    InvalidECPublicKeyException - if the extracted public key is invalid(Depending on the implementation).
  - extractStringInUncompressedForm
```
default String extractStringInUncompressedForm()
```
    Extracts the elliptic curve (EC) public key in uncompressed form encoded using base64url without padding.
    
    Returns:
    
    the public key in uncompressed form encoded using base64url without padding.
    
    Throws:
    
    InvalidECPublicKeyException - if the extracted public key is invalid(Depending on the implementation).
