JDK中可用的MessageDigest的完整列表

除了JB的答案之外,我还想提出一个解决方案来查询运行时的可用算法.这个方法当然容易地转化为一个为Cipher,SecureRandom,Mac,KeyAgreement,KeyFactory或任何其他类型的算法.

程序

import java.security.MessageDigest;
import java.security.Provider;
import java.security.Provider.Service;
import java.security.Security;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;

public class ShowHashAlgorithms {

    private static final void showHashAlgorithms(Provider prov, Class<?> typeClass) {
        String type = typeClass.getSimpleName();

        List<Service> algos = new ArrayList<>();

        Set<Service> services = prov.getServices();
        for (Service service : services) {
            if (service.getType().equalsIgnoreCase(type)) {
                algos.add(service);
            }
        }

        if (!algos.isEmpty()) {
            System.out.printf(" --- Provider %s, version %.2f --- %n", prov.getName(), prov.getVersion());
            for (Service service : algos) {
                String algo = service.getAlgorithm();
                System.out.printf("Algorithm name: \"%s\"%n", algo);


            }
        }

        // --- find aliases (inefficiently)
        Set<Object> keys = prov.keySet();
        for (Object key : keys) {
            final String prefix = "Alg.Alias." + type + ".";
            if (key.toString().startsWith(prefix)) {
                String value = prov.get(key.toString()).toString();
                System.out.printf("Alias: \"%s\" -> \"%s\"%n",
                        key.toString().substring(prefix.length()),
                        value);
            }
        }
    }

    public static void main(String[] args) {
        Provider[] providers = Security.getProviders();
        for (Provider provider : providers) {
            showHashAlgorithms(provider, MessageDigest.class);
        }
    }
}

Sun提供商输出

此代码将为Java 1.8生成以下输出.请注意,由于API提供程序的一些旧错误,提供程序版本仅作为一个提供double.因此,无法区分版本1.80或版本1.8.0.

别名低于实际实现.这些别名中的一些是对象标识符或点符号中的 OID .这些OID用于指示ASN.1编码数据格式内的算法,例如SSL/TLS中使用的X5.09v3证书.例如,1.3.14.3.2.26是{iso(1) identified-organization(3) oiw(14) secsig(3) algorithms(2) hashAlgorithmIdentifier(26)}SHA/SHA-1 的点符号和别名.
