int?aes_encrypt(char*?in,?char*?key,?char*?out)//,?int?olen)可能會設置buf長度

{

????if(!in?||?!key?||?!out)?return?0;

????unsigned?char?iv[AES_BLOCK_SIZE];//加密的初始化向量

????for(int?i=0;?i<AES_BLOCK_SIZE;?++i)//iv一般設置為全0,可以設置其他，但是加密解密要一樣就行

????????iv[i]=0;

????AES_KEY?aes;

????if(AES_set_encrypt_key((unsigned?char*)key,?128,?&aes)?<?0)

????{

????????return?0;

????}

????int?len=strlen(in);

????AES_cbc_encrypt((unsigned?char*)in,?(unsigned?char*)out,?len,?&aes,?iv,?AES_ENCRYPT);

????return?1;
