[PATCH 3/3] generate ECDSA key on existing installations

[PATCH 3/3] generate ECDSA key on existing installations

[Peter Müller]

[-- Attachment #1: Type: text/plain, Size: 2436 bytes --]

Generate ECDSA key (and sign it) in case it does not exist. That way,
httpscert can be ran on existing installations without breaking already
generated (RSA) keys.
