我想使用BouncyCastle API(v 1.52)在WildFly服务器上的Web应用程序中使用PBKDF2WithHmacSHA1-alogrithm对密码进行哈希处理。但总是当我部署我的应用程序时,我从服务器上得到一个“ClassNotFoundException org.bouncycastle.crypto.PBEParametersGenerator”。我使用Eclipse Mars和WildFly 8.2.0和9.0.1。在Eclipse中我的项目中没有出现任何错误。我已经尝试将BouncyCastle JAR添加到我的Classpath中,如另一个主题中所述,但它没有帮助。我想知道为什么我在这里或谷歌找不到任何其他结果关于这个问题,任何人都可以帮助我吗?我知道Java 8有一个PBKDF2WithHmacSHA256实现,但我想用BouncyCastle API作为替代。BouncyCastle将ClassNotFoundException部署到WildFly
这里是产生所描述的错误项目的一个非常简单的例子:
BouncyCastleHasher.java:
import java.util.Arrays;
import java.util.Base64;
import javax.faces.bean.ManagedBean;
import org.bouncycastle.crypto.PBEParametersGenerator;
import org.bouncycastle.crypto.generators.PKCS5S2ParametersGenerator;
import org.bouncycastle.crypto.params.KeyParameter;
@ManagedBean
public class BouncyCastleHasher {
private String input;
private String output;
public String hash() {
if(input!=null) {
byte[] salt = "12345678".getBytes();
PBEParametersGenerator generator = new PKCS5S2ParametersGenerator();
generator.init(PBEParametersGenerator.PKCS5PasswordToUTF8Bytes(input.toCharArray()), salt, 1);
KeyParameter params = (KeyParameter)generator.generateDerivedParameters(128);
byte[] hash = Arrays.toString(params.getKey()).getBytes();
String encodedText = Base64.getEncoder().encodeToString(hash);
setOutput(encodedText);
}
return "out";
}
public String getInput() {
return input;
}
public void setInput(String input) {
this.input = input;
}
public String getOutput() {
return output;
}
public void setOutput(String output) {
this.output = output;
}
}

项目正在建设中,但我仍然在部署中遇到同样的错误。我使用的这个相关性:' \t \t \t org.bouncycastle \t \t \t bcprov-jdk16 \t \t \t 1.46 \t \t \t 提供 \t \t ' –
