Change Log

Unreleased

Compatibility

• openssl 0.10 still uses openssl-sys 0.9, so openssl 0.9 and 0.10 can coexist without issue.

Added

• The ssl::select_next_proto function can be used to easily implement the ALPN selection callback in a "standard" way.
• FIPS mode support is available in the fips module.
• Accessors for the Issuer and Issuer Alternative Name fields of X509 certificates have been added.

Changed

• All constants have been moved to associated constants of their type. For example, bn::MSB_ONE is now bn::MsbOption::ONE.

• Asymmetric key types are now parameterized over what they contain. In OpenSSL, the same type is used for key parameters, public keys, and private keys. Unfortunately, some APIs simply assume that certain components are present and will segfault trying to use things that aren't there.

  The pkey module contains new tag types named Params, Public, and Private, and the Dh, Dsa, EcKey, Rsa, and PKey have a type parameter set to one of those values. This allows the Signer constructor to indicate that it requires a private key at compile time for example. Previously, Signer would simply segfault if provided a key without private components.

• ALPN support has been changed to more directly model OpenSSL's own APIs. Instead of a single method used for both the server and client sides which performed everything automatically, the SslContextBuilder::set_alpn_protos and SslContextBuilder::set_alpn_select_callback handle the client and server sides respectively.

• SslConnector::danger_connect_without_providing_domain_for_certificate_verification_and_server_name_indication has been removed in favor of new methods which provide more control. The ConnectConfiguration::use_server_name_indication method controls the use of Server Name Indication (SNI), and the ConnectConfiguration::verify_hostname method controls the use of hostname verification. These can be controlled independently, and if both are disabled, the domain argument to ConnectConfiguration::connect is ignored.

• Shared secret derivation is now handled by the new derive::Deriver type rather than pkey::PKeyContext, which has been removed.

• ssl::Error is now no longer an enum, and provides more direct access to the relevant state.

Removed

• All deprecated APIs have been removed.
• NPN support has been removed. It has been supersceded by ALPN, and is hopefully no longer being used in practice. If you still depend on it, please file an issue!
• Some ssl::SslOptions flags have been removed as they no longer do anything.
