我只是偶然发现这个问题,因为我自己也很好奇。由于没有人回答,我尝试了一下,它确实有效(至少对于 AES CTR 128 解密),所以我大胆猜测它也适用于其他类型。如果您有兴趣,这是我的代码示例。

const unsigned char key[16] = { 0x2b, 0x7e, 0x15, 0x16,
0x28, 0xae, 0xd2, 0xa6,
0xab, 0xf7, 0x15, 0x88,
0x09, 0xcf, 0x4f, 0x3c };
const unsigned char IV[16] = { 0xf0, 0xf1, 0xf2, 0xf3,
0xf4, 0xf5, 0xf6, 0xf7,
0xf8, 0xf9, 0xfa, 0xfb,
0xfc, 0xfd, 0xfe, 0xff };
unsigned char test[16] = { 0x6b, 0xc1, 0xbe, 0xe2,
0x2e, 0x40, 0x9f, 0x96,
0xe9, 0x3d, 0x7e, 0x11,
0x73, 0x93, 0x17, 0x2a };
EVP_CIPHER_CTX mCtx;
EVP_DecryptInit(&mCtx, EVP_aes_128_ctr(), key, IV);
int out_size;
EVP_DecryptUpdate(&mCtx, test, &out_size, test, 16);
