59 +In order to generate an eliptic curve key with the `req` command, a suitable parameters file has to be generated first:
60 +
61 +```bash
62 +openssl genpkey -genparam -algorithm EC -pkeyopt ec_paramgen_curve:P-256 -out ec-p-256-params.pem
63 +```
64 +
65 +Instead of the `P-256` curve, another curve can be chose of course. This parameter file can then be used with the `-newkey` parameter of the `req` command:

67 +```bash
68 +openssl req -out cert.csr -keyout cert.key -nodes -newkey params:ec-p-256-params.pem -sha256
