Aki, I just used the "EC key" instructions from the Dovecot MailCrypt wiki:

In order to generate an EC key, you must first choose a curve from the 
output of this command:
 > openssl ecparam -list_curves

If you choose the curve prime256v1, generate and EC key with the command:
 > openssl ecparam -name prime256v1 -genkey | openssl pkey -out 
ecprivkey.pem

Then generate a public key out of your private EC key
 > openssl pkey -in ecprivkey.pem -pubout -out ecpubkey.pem
