JDK中可用的MessageDigest的完整列表 [英] Complete list of MessageDigest available in the JDK
问题描述
在Java中，可用的MessageDigests取决于哪些您已配置/安装的安全提供程序。但是假设只是一个正常的JDK8安装（在我的情况下为1.8.0_11），什么是可用的哈希算法列表？从文档中的示例，很明显MD5，SHA1和SHA-256是可用的，但我似乎不能得到一个完整的，权威的列表。
除了JB的答案，我想要提出一个解决方案，查询运行时可用的算法。这种方法当然很容易转换为 Cipher ， SecureRandom ， Mac ， KeyAgreement ， KeyFactory 或任何其他类型 p>

Sun提供程序输出
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 double 存在。由于这个原因，不可能区分版本1.80或版本1.8.0。
别名低于实际的实现。其中一些别名是对象标识符或OID的点符号。这些OID用于指示来自ASN.1编码数据格式（如在SSL / TLS中使用的X5.09v3证书）的算法。例如， 1.3.14.3.2.26 是 {iso（1）identify-organization（3）oiw（14）secsig ）algorithm（2）hashAlgorithmIdentifier（26）} 和SHA / SHA-1的别名。

I've searched high and low for this, but I can't seem to get a straight answer.
In Java, the available MessageDigests are determined by which security providers you have configured/installed. But assuming just a normal JDK8 install (1.8.0_11 in my case), what's the list of hash algorithms that are available? From examples in the docs, it's obvious MD5, SHA1 and SHA-256 are available, but I can't seem to get a complete, authoritative list.
Does this list exist, or how do I go about finding out for my particular install?
In addition to JB's answer, I would like to propose a solution that queries the runtime for available algorithms. This method is of course easily converted to one for Cipher, SecureRandom, Mac, KeyAgreement, KeyFactory or any other type of algorithm.

Sun provider output
This code will generate the following output for Java 1.8. Note that because of some old mistake by the API providers, the provider version is only present as a double. It is not possible to distinguish between version 1.80 or version 1.8.0 because of this.
The aliases are below the actual implementations. Some of these aliases are Object Identifiers or OID's in dot notation. These OID's are used to indicate algorithms from within ASN.1 encoded data formats such as X5.09v3 certificates as used within SSL/TLS. For instance, 1.3.14.3.2.26 is the dot notation for {iso(1) identified-organization(3) oiw(14) secsig(3) algorithms(2) hashAlgorithmIdentifier(26)} and the alias for SHA/SHA-1.
