```
public static void registerPair(boolean newKeyAllowed)
                         throws java.security.GeneralSecurityException
```
    Registers the EcdsaSignKeyManager and the EcdsaVerifyKeyManager with the registry, so that the the Ecdsa-Keys can be used with Tink.
    
    Throws:
    
    java.security.GeneralSecurityException
  - ecdsaP256Template
```
public static final KeyTemplate ecdsaP256Template()
```
    Returns:
    
    A KeyTemplate that generates new instances of ECDSA keys with the following parameters:
    
    Hash function: SHA256
    Curve: NIST P-256
    Signature encoding: DER (this is the encoding that Java uses).
    Prefix type: KeyTemplate.OutputPrefixType.TINK.
  - rawEcdsaP256Template
```
public static final KeyTemplate rawEcdsaP256Template()
```
    Returns:
    
    A KeyTemplate that generates new instances of ECDSA keys with the following parameters:
    
    Hash function: SHA256
    Curve: NIST P-256
    Signature encoding: IEEE_P1363 (this is the encoding that JWS and WebCrypto use).
    Prefix type: RAW (no prefix).
    Keys generated from this template create raw signatures of exactly 64 bytes. It is compatible with JWS and most other libraries.
