使用OpenSSL库在C ++中生成SHA-3哈希 [英] Generate SHA-3 hash in C++ using OpenSSL library

问题描述

我已经广泛搜索了一个代码示例，该示例使用OpenSSL最近实现的SHA-3算法进行哈希处理，但找不到任何示例.在SHA-1和SHA-3上有代码示例，但是在库文件夹中快速搜索显示OpenSSL v1.1.1中甚至没有SHA3函数名称?

I've searched extensively for a code example that uses OpenSSL's recently implemented SHA-3 algorithm for hashing but couldn't find any. There are code examples on SHA-1 and SHA-3 but a quick search in the library folders reveal that there isn't even a SHA3 function name in OpenSSL v1.1.1?

我到处搜索过，但这是相对较新的内容，因此我无法找到有关新算法的任何特定信息.

I've searched everywhere but this is relatively new and I have not been able to track down any information specifically regarding the new algorithm.

我发现此线程使用OpenSSL库在C ++中生成SHA哈希涵盖了SHA-1和SHA-2，但是库中实际上没有SHA3函数-Keccak1600看起来像SHA-3的名字吗?

I found this thread that Generate SHA hash in C++ using OpenSSL library covers SHA-1 and SHA-2 but there isn't actually a SHA3 function in the library - Keccak1600 seems like name for SHA-3?

推荐答案

此页面上有一些用于生成哈希的通用示例代码:

There is some generic sample code for generating a hash on this page:

https://wiki.openssl.org/index.php/EVP_Message_Digests

该特定代码生成SHA256哈希.要将其转换为使用SHA3，请将EVP_sha256()的两个实例替换为EVP_sha3_224()，EVP_sha3_256()，EVP_sha3_384()或EVP_sha3_512()之一.

That particular code generates a SHA256 hash. To convert it to use SHA3 instead, replace the two instances of EVP_sha256() with one of EVP_sha3_224(), EVP_sha3_256(), EVP_sha3_384() or EVP_sha3_512() as appropriate.
