org.openeuler.sun.security.ec.ECKeyFactory

public final class ECKeyFactory
extends KeyFactorySpi

KeyFactory for EC keys. Keys must be instances of PublicKey or PrivateKey and getAlgorithm() must return "EC". For such keys, it supports conversion between the following: For public keys: . PublicKey with an X.509 encoding . ECPublicKey . ECPublicKeySpec . X509EncodedKeySpec For private keys: . PrivateKey with a PKCS#8 encoding . ECPrivateKey . ECPrivateKeySpec . PKCS8EncodedKeySpec This class is a modified version of the ECKeyFactory class in the Sun library, designed to adapt to the SM2 algorithm.

toECKey

public static ECKey toECKey(Key key)
                     throws InvalidKeyException

Static method to convert Key into a useable instance of ECPublicKey or ECPrivateKey. Check the key and convert it to a Sun key if necessary. If the key is not an EC key or cannot be used, throw an InvalidKeyException. The difference between this method and engineTranslateKey() is that we do not convert keys of other providers that are already an instance of ECPublicKey or ECPrivateKey. To be used by future Java ECDSA and ECDH implementations.

抛出:

InvalidKeyException

checkKey

private static void checkKey(ECKey key)
                      throws InvalidKeyException

Check that the given EC key is valid.

抛出:

InvalidKeyException

engineTranslateKey

protected Key engineTranslateKey(Key key)
                          throws InvalidKeyException

Translate an SM2 key into a Sun SM2 key. If conversion is not possible, throw an InvalidKeyException. See also JCA doc.
