openssl3.2 - EVP_CIPHER_fetch算法名称字符串(参数2)的有效值列表

概述

进行加解密时, 先要选一个算法.
如果使用EVP接口, 要调用EVP_CIPHER_fetch得到EVP算法指针.

EVP_CIPHER *cipher = NULL;
// .../* Fetch the cipher implementation */if ((cipher = EVP_CIPHER_fetch(libctx, "AES-256-GCM", propq)) == NULL)goto err;

看资料上讲, 不建议用字符串来找EVP算法指针, 因为有可能写错.
一旦写错, 就得不到有效的cipher.
如果知道写错了, 如何写对, 到底有啥标准, 不好确定.
通过有源码调试openssl.exe + SI来搜索, 找到了算法名称字符串的确切集合.
等写错了/或者不记得正确的算法名称该咋写, 就可以去openssl源码对应文件中去找.

如何找到算法名称字符串列表?

也是边调试边猜测, 毕竟openssl3.2是很庞大的第三方代码. 只要能正常用起来就行. 只关心自己关注的点, 不没事找事.

断在了 ossl_default_provider_init(), 这里会将默认算法集合赋值给上下文

int ossl_default_provider_init(const OSSL_CORE_HANDLE *handle,const OSSL_DISPATCH *in,const OSSL_DISPATCH **out,void **provctx)
{// ...*out = deflt_dispatch_table;ossl_prov_cache_exported_algorithms(deflt_ciphers, exported_ciphers); // break here// 查看变量 deflt_ciphers, 就会发现, 这就是有效算法集合.return 1;
}

deflt_ciphers 就是默认算法集合, 一共130个算法.

PROV_NAMES_X(e.g. PROV_NAMES_AES_256_ECB) 就是算法字符串的宏定义
但是在VS2019中无法转到宏定义, 这时, 配置SI搜索, 可以确定 PROV_NAMES_AES_256_ECB定义的头文件为

name.h中的 PROV_NAMES_X的宏就是算法名称字符串.
有的算法名称有别名, 在宏定义的字符串中用’:'分开, 如下:

#define PROV_NAMES_AES_256_GCM "AES-256-GCM:id-aes256-GCM:2.16.840.1.101.3.4.1.46"

我们在程序中写的算法字符串可以使用由’:'分隔开的别名之一就行.
e.g. 为了使用EVP_CIPHER_fetch参数2, 可以写的参数2名称如下3种都行:

正好我在实验的aesgcm.c, 使用的就是"AES-256-GCM", 来试试别名行不行?

    // 这个实验是在解密函数中实验的, 以下3种写法都可以正确解密密文为明文, 说明我猜测的正确的// #define PROV_NAMES_AES_256_GCM "AES-256-GCM:id-aes256-GCM:2.16.840.1.101.3.4.1.46"// if ((cipher = EVP_CIPHER_fetch(libctx, "AES-256-GCM", propq)) == NULL)// if ((cipher = EVP_CIPHER_fetch(libctx, "id-aes256-GCM", propq)) == NULL)if ((cipher = EVP_CIPHER_fetch(libctx, "2.16.840.1.101.3.4.1.46", propq)) == NULL){goto err;}

备注

有了这个知识点后, 就不怕EVP_CIPHER_fetch()参数2写错了, 或者想不起来怎么写:P
也就不用自己避开EVP_CIPHER_fetch(), 来指定算法指针那么麻烦.
如果换个算法, 就换个算法名称字符串宏就搞定.
如果自己将算法名称字符串写错了, 就去name.h中找一下, 确认一下即可.
