Java中的BouncyCastle

Question

我在我的程序中使用了以下代码将字节转换为公钥

Security.addProvider(new BouncyCastleProvider());
         X509EncodedKeySpec x509keyspec=new X509EncodedKeySpec(b);


         KeyFactory keyfact=KeyFactory.getInstance("RSA","BC");
         Key pubkey=keyfact.generatePublic(x509keyspec); 

我已经导入了“导入org.bouncycastle.jce.provider.BouncyCastleProvider;"，。

我已经将Bouncycastle.jar文件添加到我的jre7/lib/ext文件夹中，并通过在编译代码时添加以下行security.provider.11=org.bouncycastle.jce.provider.BouncyCastleProvider在javasecurity文件中进行了更改

Reverse.java:14: error: cannot find symbol
import java.security.spec.x509EncodedKeySpecs;
                         ^
symbol:   class x509EncodedKeySpecs
location: package java.security.spec

Reverse.java:16: error: package org.bouncycastle.jce.provider does not exist
import org.bouncycastle.jce.provider.BouncyCastleProvider;

Reverse.java:49: error: cannot find symbol
Security.addProvider(new BouncyCastleProvider());
                                  ^
  symbol:   class BouncyCastleProvider
  location: class Reverse

Answer 1

两个问题：

• 这个类被命名为X509EncodedKeySpec，而不是x509EncodedKeySpecs。修复您的JAR确保当您编译和运行代码时，BouncyCastle statement.
• Make位于类路径上。
