## Public_Key 0.9

### Improvements and New Features

Updated ssl to ignore CA certs that violate the asn1-spec for a certificate, and updated public key asn1 spec to handle inherited DSS-params.

Own Id: OTP-7884

Changed ssl implementation to retain backwards compatibility for old option {verify, 0} that shall be equivalent to {verify, verify_none}, also separate the cases unknown ca and selfsigned peer cert, and restored return value of deprecated function public_key:pem_to_der/1.

Own Id: OTP-8858

Better handling of v1 and v2 certificates. V1 and v2 certificates does not have any extensions so then validate_extensions should just accept that there are none and not end up in missing_basic_constraints clause.

Own Id: OTP-8867

Changed the verify fun so that it differentiate between the peer certificate and CA certificates by using valid_peer or valid as the second argument to the verify fun. It may not always be trivial or even possible to know when the peer certificate is reached otherwise.

*** POTENTIAL INCOMPATIBILITY ***
