Converting ECPrivateKey SEC1 to PCKS8

[romgrm]

Hello ! I'm currently generating an EC keypair that I encode in PEM format.

The back end to which I send the keys tells me that they need the Pkcs8 format and not SEC1.

I wonder if it's possible with this lib, to convert an ECPrivateKey to Pcks8? Or is it only for RSA keys?

Thanks :)
