Bouncy Castle NTRU加密导出公钥

Question

我得到了AsymmetricKeyParameter a = asymmetricCipherKeyPair.getPublic（）; 我花了几个小时在这个上面，并且不知道如何将公钥变成一个字节序列。任何想法？

 NTRUEncryptionKeyPairGenerator ntruEncryptionKeyPairGenerator = new NTRUEncryptionKeyPairGenerator();
        long begin = System.currentTimeMillis();
        NTRUEncryptionKeyGenerationParameters ntruEncryptionKeyPairGeneratorParameters = NTRUEncryptionKeyGenerationParameters.EES1087EP2;


        ntruEncryptionKeyPairGenerator.init(ntruEncryptionKeyPairGeneratorParameters);


        AsymmetricCipherKeyPair asymmetricCipherKeyPair = ntruEncryptionKeyPairGenerator.generateKeyPair();

我试过

AsymmetricKeyParameter a = asymmetricCipherKeyPair.getPublic();
SubjectPublicKeyInfo info = SubjectPublicKeyInfoFactory.createSubjectPublicKeyInfo(a);

但它会抛出“无法识别的关键参数。”

Answer 1

((NTRUEncryptionPublicKeyParameters)asymmetricCipherKeyPair.getPublic()).getEncoded();
