本文介绍了获取字符串的SHA-256串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一些字符串,我想用C#的SHA-256散列函数散列它。我想是这样的:
I have some string and I want to hash it with the SHA-256 hash function using C#. I want something like this:
string hashString = sha256_hash("samplestring");
是不是有什么内置的框架来做到这一点?
Is there something built into the framework to do this?
推荐答案
的实施可能会像
public static String sha256_hash(String value) {
StringBuilder Sb = new StringBuilder();
using (SHA256 hash = SHA256Managed.Create()) {
Encoding enc = Encoding.UTF8;
Byte[] result = hash.ComputeHash(enc.GetBytes(value));
foreach (Byte b in result)
Sb.Append(b.ToString("x2"));
}
return Sb.ToString();
}
编辑:LINQ实现,它是比较的简洁的,但是,很可能的的可读性的:
LINQ implementation which is more concise, but, probably, less readable:
public static String sha256_hash(String value) {
using (SHA256 hash = SHA256Managed.Create()) {
return String.Join("", hash
.ComputeHash(Encoding.UTF8.GetBytes(value))
.Select(item => item.ToString("x2")));
}
}
