With this command the ciphers that curl is allowed to use are selected. First all possible ciphers are selected (ALL) and then some weak ciphers (!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4) are excluded. By excluding all Diffie-Hellman ciphers (!DH) we address the issue that curl is mentioning. The last thing (@STRENGTH) is to sort the ciphers according to their strength.
