使用 Java 存储 SHA2 密码

我正在尝试进行 XML-RPC 调用，该调用需要对特定字符串进行 HmacSHA-256 哈希处理。我目前正在使用带有以下代码的 Jasypt 库：

StandardPBEStringEncryptor sha256 = new StandardPBEStringEncryptor();
          sha256.setPassword(key);
          sha256.setAlgorithm("PBEWithHmacSHA2");

在尝试使用 sha256.encrypt(string) 时，我收到此错误：

Exception in thread "main" org.jasypt.exceptions.EncryptionInitializationException: java.security.NoSuchAlgorithmException: PBEWithHmacAndSHA256 SecretKeyFactory not available
     at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.initialize(StandardPBEByteEncryptor.java:597)
     at org.jasypt.encryption.pbe.StandardPBEStringEncryptor.initialize(StandardPBEStringEncryptor.java:488)
     at org.jasypt.encryption.pbe.StandardPBEStringEncryptor.encrypt(StandardPBEStringEncryptor.java:541)
     at nysenateapi.XmlRpc.main(XmlRpc.java:52)
    Caused by: java.security.NoSuchAlgorithmException: PBEWithHmacAndSHA256 SecretKeyFactory not available
     at javax.crypto.SecretKeyFactory.(DashoA13*..)
     at javax.crypto.SecretKeyFactory.getInstance(DashoA13*..)
     at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.initialize(StandardPBEByteEncryptor.java:584)
     ... 3 more

我下载了 JCE 加密扩展并将 jar 放在我的构建路径中，但这似乎没有做了任何事。我已经尝试在上面的 setAlgorithm 中使用多种组合，包括“PBE”、“PBEWithSha”(1|2|128|256)?、“PBEWithHmacSha”等。

我也尝试使用 BouncyCastle，但我没有任何组合那里也有运气。任何帮助或指导表示赞赏！

I'm attempting to make a XML-RPC call that requires HmacSHA-256 hashing of a particular string. I'm currently using the Jasypt library with the following code:

StandardPBEStringEncryptor sha256 = new StandardPBEStringEncryptor();
          sha256.setPassword(key);
          sha256.setAlgorithm("PBEWithHmacSHA2");

On trying to use sha256.encrypt(string) I get this error:

Exception in thread "main" org.jasypt.exceptions.EncryptionInitializationException: java.security.NoSuchAlgorithmException: PBEWithHmacAndSHA256 SecretKeyFactory not available
     at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.initialize(StandardPBEByteEncryptor.java:597)

    Caused by: java.security.NoSuchAlgorithmException: PBEWithHmacAndSHA256 SecretKeyFactory not available

     at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.initialize(StandardPBEByteEncryptor.java:584)
     ... 3 more

I downloaded the JCE Cryptography extension and placed the jars in my buildpath, but that doesn't seem to have done anything. I've tried using a number of combinations in setAlgorithm above, including "PBE", "PBEWithSha"(1|2|128|256)?, "PBEWithHmacSha", etc.

I also tried using BouncyCastle but I didn't have any luck there either. Any help or guidance appreciated!

正如 @Rook 所正确指出的，您需要指定包含加密算法的 PBE 算法。其中两个示例是 "PBEWithSHA1AndDESede"，它由 SunJCE 提供程序和 Bouncycastle JCE 提供程序支持的 "PBEWITHSHA256AND128BITAES-CBC-BC"。

这些评论很有帮助，但我想我问了错误的问题。我想做的是模仿 PHP 函数 hash_hmac('sha256',string,key)...

我最终使用了以下代码：

Mac mac = Mac.getInstance("HmacSha256");
SecretKeySpec secret = new SecretKeySpec(key.getBytes(), "HmacSha256");
mac.init(secret);
byte[] shaDigest = mac.doFinal(phrase.getBytes());
String hash = "";
for(byte b:shaDigest) {
    hash += String.format("%02x",b);
}

不过，谢谢您的指导。将来肯定会对我有帮助。

The comments were helpful but I guess I was asking the wrong question. What I was looking to do was mimic the PHP function hash_hmac('sha256',string,key)...

I ended up using the following code:

Mac mac = Mac.getInstance("HmacSha256");
SecretKeySpec secret = new SecretKeySpec(key.getBytes(), "HmacSha256");
mac.init(secret);
byte[] shaDigest = mac.doFinal(phrase.getBytes());
String hash = "";
for(byte b:shaDigest) {
    hash += String.format("%02x",b);
}

Thanks for the guidance, though. Will surely help me in the future.
