Is there a way to run openssl.exe faster? For example you can run gzip with the argument --fast. Is there anything like that for openssl?

If not is there an encryption type that is known to be faster - not concerned if the speed means I sacrifice encryption complexity/protection. Currently I am using aes-256-cbc and its very slow for 100mb files (takes about 30 seconds).

    Can you leverage the AES-NI cpu extentions found in newer CPU’s with `-evp` ? http://ask.xmodulo.com/check-aes-ni-enabled-openssl.html – HBruijn Dec 10 '17 at 09:27
  • Just have a look into the ciphers supported by your OpenSSL and run tests with all of them. – Tero Kilkanen Dec 10 '17 at 11:19
