Examples with OpenSSHPrivateKeySpec org.bouncycastle.jcajce.spec.OpenSSHPrivateKeySpec used on opensource projects

Example 1 with OpenSSHPrivateKeySpec

use of org.bouncycastle.jcajce.spec.OpenSSHPrivateKeySpec in project hutool by looly.

the class SM2Test method getPublicKeyByPrivateKeyTest.

@Test

    PrivateKey privateKey = KeyUtil.generatePrivateKey("sm2", new OpenSSHPrivateKeySpec(SecureUtil.decode(priKey)));
    final ECPrivateKeyParameters privateKeyParameters = ECKeyUtil.toPrivateParams(privateKey);
    final SM2 sm2 = new SM2(privateKeyParameters, ECKeyUtil.getPublicParams(privateKeyParameters));
    String src = "Sm2Test";

    byte[] dec = sm2.decrypt(data, KeyType.PrivateKey);
    Assert.assertArrayEquals(dec, src.getBytes(StandardCharsets.UTF_8));
