问题 So I have (this doesn’t work b/c hex is probably wrong and the key and the IV are not converted correctly): (aesKey and aesIV are provided as hex strings from Third Party) They look something like this (not the same but should be enough to work with I replaced some values in the keys so they aren’t exactly the same: <cfparam name="aesKey" default="C20648780E8843795325F3BA5EC43183C8BFA2D26B5470BC309ED5BA6B142EFA"/> <cfparam name="aesIV" default="A53F0A6E6972A0095CFFDBE4F47C3CF8"/> <cfset token

问题 I did AES/ECB/PKCS5Padding encryption in JAVA . Now I am looking for equivalent method in C/C++ . I did manage to encrypt in C using the following code : const unsigned char *key = (unsigned char *)"A2XTXFEQFOPZFAKXFOPZFAK5"; unsigned char input[] = {"Hello World"}; int iLen = strlen((char*)input); int len = 0; if(iLen % 16 == 0){ len = iLen; } else{ len = (iLen/16)*16 + 16; } unsigned char output[len]; //next 16bit AES_KEY enc_key; AES_set_encrypt_key(key, strlen((char*)key)*8, &enc_key);

问题 I need to insert a 128 hex key to cipher by blocks (16) a string content, and then I want to decrypyt that string(crypted) to a plain text. Sometimes I have the same output, but not totaly correct! I am doing this right?! My code now: #include <openssl/aes.h> #include <openssl/rand.h> #include <openssl/hmac.h> #include <openssl/buffer.h> #include <stdio.h> #include <string.h> #include <stdlib.h> #include <math.h> // Code example uses partail code from: http://stackoverflow.com/questions
