示例1: decrypt
import org.bouncycastle.asn1.DEROctetString; //導入方法依賴的package包/類
public static byte[] decrypt(byte[] privateKey, byte[] encryptedData) throws IOException {
if (privateKey == null || privateKey.length == 0) {
return null;
}
if (encryptedData == null || encryptedData.length == 0) {
return null;
}
byte[] enc = new byte[encryptedData.length];
System.arraycopy(encryptedData, 0, enc, 0, encryptedData.length);
SM2 sm2 = SM2.Instance();
BigInteger userD = new BigInteger(1, privateKey);
ByteArrayInputStream bis = new ByteArrayInputStream(enc);
ASN1InputStream dis = new ASN1InputStream(bis);
DERObject derObj = dis.readObject();
ASN1Sequence asn1 = (ASN1Sequence) derObj;
DERInteger x = (DERInteger) asn1.getObjectAt(0);
DERInteger y = (DERInteger) asn1.getObjectAt(1);
ECPoint c1 = sm2.ecc_curve.createPoint(x.getValue(), y.getValue(), true);
Cipher cipher = new Cipher();
cipher.initDec(userD, c1);
