什么是确切的替代API，而不是openssl 1.1.0中的AES_ctr128_encrypt? [英] What is exact alternate API instead of AES_ctr128_encrypt from openssl 1.1.0?

问题描述

我需要在CTR模式下使用128位AES算法从openssl库进行加密. 但是似乎从openssl 1.1.0g中删除了相应的函数AES_ctr128_encrypt.因为出现以下错误:-

I need to use 128 bit AES algrothm in CTR mode for encryption from the openssl library. But it seems that the corresponding function AES_ctr128_encrypt is removed from openssl 1.1.0g. because I get below error:-

互联网上的文档或参考文献不建议使用AES CTR模式的替代功能. 带有openssl 1.1.0g的AES_ctr128_encrypt的确切替代方案是什么?

Documentation or references from internet does not suggest the alternate function for AES CTR mode. What is the exact alternate for AES_ctr128_encrypt with openssl 1.1.0g?

推荐答案

要想简单地回答问题，我只想补充一点:不要忘记包括以下标头:

To mnistic's answer, I would only add that you should not forget to include these headers:

• openssl/aes.h
• openssl/modes.h

那么这:

AES_ctr128_encrypt(
  cipher_in,
  plaintext_out,
  bytes_length,
  &cipher->aes_key->key,
  cipher->aes_key->IV,
  counter,
  &offset);

将成为:

#include <openssl/aes.h>
#include <openssl/modes.h>
.
.
.
CRYPTO_ctr128_encrypt(
  cipher_in,
  plaintext_out,
  bytes_length,
  &cipher->aes_key->key,
  cipher->aes_key->IV,
  counter,
  &offset, 
  (block128_f)AES_encrypt);
