Upgrade to release 0.17.0:
- Keys that use explicit curve parameters can now be read and
written. Reading of explicit curves can be disabled by using
the valid_curve_encodings keyword argument in
VerifyingKey.from_pem(), VerifyingKey.from_der(),
SigningKey.from_pem(), and SigningKey.from_der().
- Keys can now be written with use of explicit curve parameters,
use curve_parameters_encoding keyword argument of
VerifyingKey.to_pem(), VerifyingKey.to_der(),
SigningKey.to_pem(), or SigningKey.to_der() to specify the
format. By default named_curve will be used, unless the curve
doesn't have an associated OID (as will be the case for an
unsupported curve), then explicit encoding will be used.
- Allow specifying acceptable point formats when loading public
keys (this also fixes a minor bug where python-ecdsa would
accept raw encoding for points in PKCS#8 files). Set of accepted
encodings is controlled by valid_encodings keyword argument in
ECDH.load_received_public_key_bytes(),
VerifyingKey.from_string(), VerifyingKey.from_pem(),
VerifyingKey.from_der().
- PointJacobi and Point now inherit from AbstractPoint that
implements the methods for parsing points. That added
from_bytes() and to_bytes() methods to both of them.
- Curve parameters can now be read and written to PEM and DER
files. The Curve class supports new to_der(), from_der(),
to_pem(), and from_pem() methods.
