java – 哪个提供商负责AES / CTR / NoPadding？
作者：互联网
有关我的实施的信息
下面的代码片段使用AES密码和CTR操作模式突出显示了当前加密对象的实现.
import javax.crypto.Cipher;
public abstract class Crypto {
private static final String CIPHER_ALGORITHM = "AES/CTR/NoPadding";
private String AesKeyString = "ByWelFHCgFqivFZrWs89LQ==";
private void setKey() throws NoSuchAlgorithmException{
byte[] keyBytes;
keyBytes = Base64.getDecoder().decode(AesKeyString);
aesKey = new SecretKeySpec(keyBytes, "AES");
}
protected byte[] execute(int mode, byte[] target, byte[] iv)
throws Exception{
Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
IvParameterSpec ivSpec = new IvParameterSpec(iv);
cipher.init(mode, aesKey, ivSpec);
return cipher.doFinal(target);
}
}
As far as I’m concerned,getInstance()方法从支持此转换的第一个Provider返回实现请求转换的Cipher对象.

即使我没有看到任何支持“AES / CTR / NoPadding”算法的提供程序,execute()方法也没有抛出NoSuchAlgorithmException,因此我认为这个算法是由之前的一个提供程序支持的.
题
>正在调用以前的哪些提供商来实现设想
密码对象支持“AES / CTR / NoPadding”算法？
注意
提供商列表太长,不适合这篇文章,如果您需要有关未提及的特定提供商的任何信息,请告诉我.
解决方法:
您可以在任何Cipher(或MessageDigest等)上调用getProvider().如果您使用“AES / GCM / NoPadding”为密码执行此操作,您将获得SunJCE提供程序.当然,您不会获得其他服务信息.
要获取有关AES密码的服务信息,请尝试以下代码：
public static void main(String[] args) {
Provider[] provs = Security.getProviders();
for (Provider provider : provs) {
Service service = provider.getService("Cipher", "AES");
if (service == null) {
continue;
}
String modes = service.getAttribute("SupportedModes");
if (modes != null && modes.matches("(?i).*CTR.*")) {
System.out.println(service);
}
}
}
这将输出：
SunJCE: Cipher.AES -> com.sun.crypto.provider.AESCipher$General
aliases: [Rijndael]
attributes: {SupportedPaddings=NOPADDING|PKCS5PADDING|ISO10126PADDING, SupportedKeyFormats=RAW, SupportedModes=ECB|CBC|PCBC|CTR|CTS|CFB|OFB|CFB8|CFB16|CFB24|CFB32|CFB40|CFB48|CFB56|CFB64|OFB8|OFB16|OFB24|OFB32|OFB40|OFB48|OFB56|OFB64|GCM|CFB72|CFB80|CFB88|CFB96|CFB104|CFB112|CFB120|CFB128|OFB72|OFB80|OFB88|OFB96|OFB104|OFB112|OFB120|OFB128}
所以你有它：AES,CTR和NoPadding.
不可否认,提供商的服务界面并没有得到很好的描述,因此获取这些信息需要一些令人费解的事情.
