Hi, We are using openssl-1.0.1e version and also AESNI is enabled in BIOS.
I am trying to measure the AES-256-CBC algorithm performance for decryption of 256bytes buffer size. But I am not getting the numbers matching with the 'openssl speed' tool. I saw it uses AESNI if we call the EVP* API, so I have used EVP* APIs in my sample code (code snippet below). <code snip> EVP_CipherInit(&ctx, EVP_aes_256_cbc(), &key_block[40], &iv_input[0], 0); clock_gettime(CLOCK_REALTIME, &tspec_start); outlen1 = EVP_Cipher(&ctx, &outbuf[0], &inbuf[0], sizeof(inbuf)); clock_gettime(CLOCK_REALTIME, &tspec_end); </code snip> With this I got the number close to135000k Bytes/sec for 256bytes of buffer. But the 'openssl speed -evp ' shows around 569344.00k Bytes/sec. Could someone please advise if I am missing anything? Measuring the time taken by EVP_Ciphrer() API - is it not a valid way to calculate the performance numbers? -- Thanks, Nilesh ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
