使用EVP API可以使用AES CTR模式加密吗？

本文介绍了使用EVP API可以使用AES CTR模式加密吗？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

我是OpenSSL的新手。我明白加密应该使用作为所有密码的通用接口的EVP API执行。 AES CTR模式似乎存在于我拥有的OpenSSL版本中，但EVP_aes_128_ctr的定义在evp.h中被禁用：

I'm new to OpenSSL. I understand that encryption should be performed using the EVP API which acts as a common interface to all the ciphers. AES CTR mode seems to be present in the version of OpenSSL that I have, but the definition for EVP_aes_128_ctr is disabled in evp.h:

#if 0 const EVP_CIPHER *EVP_aes_128_ctr(void); #endif

任何想法为什么会这样？我可以删除#if 0吗？要获取128位AES CTR模式加密在OpenSSL中工作的任何其他指针将不胜感激！

Any idea why this is? Can I just remove the #if 0? Any other pointers on getting 128 bit AES CTR mode encryption to work in OpenSSL would be appreciated!

谢谢！

推荐答案

Btw，看起来像这样的答案是没有，还没有。但也许很快我发现这个电子邮件主题表明，解决此问题的修补程序可能已于2010年6月提交：

Btw, it looks like the answer to this is no, not yet. But maybe soon. I found this email thread indicating that a patch to address this issue may have been submitted in June 2010:

但是当我从SVN下载最新的开发分支机构时，执行副总裁仍然没有启用AES点击率。我最终只是直接实现它，我发现这个链接有帮助：

But when I downloaded the latest development branch from SVN, AES CTR was still not enabled in EVP. I ended up just implementing it directly, for which I found this link helpful:
