Sourced from rustls's releases.

0.22.1

• TLS 1.2 servers now remove session tickets after observing a failure to decrypt, preventing future resumption with the same unusable ticket.
• The rustls_pki_types crate is now re-exported as rustls::pki_types.
• The crate examples examples have been updated to use the rustls::pki_types re-export.
• The quic::PacketKey and quic::HeaderProtectionKey traits are now Send + Sync.
• Performance improvements to the MessageDeframer internals.
• Small documentation improvements.

Full Changelog: rustls/rustls@v/0.22.0...v/0.22.1

0.22.0

New features

• Configurable cryptography providers. The cryptography used by rustls is represented by the CryptoProvider trait. ring is now optional, but remains the default provider.
• Certificate revocation list (CRL) support. The default certificate verifier used in rustls can now be configured with CRLs to control revocation of client and server certificates.
• Optional support for cryptography from aws-lc-rs. Once the certification process completes , we will support FIPS mode using aws-lc-rs.
• Separate configuration of root hints in client certificate verifier. To deal with cross-signed client certificate topologies, the list of hints sent to a client can now be configured. The default behaviour remains to send the names of the configured root certificates.

Related libraries

There are some related libraries in the rustls ecosystem. If you depend on these libraries, you'll need at least these versions to be compatible with rustls 0.22:

rustls-pki-types = { version = "1" }
webpki-roots = { version = "0.26" }
rustls-webpki = { version = "0.102" }
rustls-pemfile = { version = "2" }
rustls-native-certs = { version = "0.7"}

Breaking changes

• Remove support for SCTs provided via TLS extension. Ecosystem support for this is rare compared to inclusion of SCTs in certificates.
• Rename WebPkiVerifier to WebPkiServerVerifier and add WebPkiClientVerifier.
• Remove default trait implementations in ServerCertVerifier/ClientCertVerifier so the trait doesn't depend on webpki. Instead the previous implementations are exposed as rustls::crypto::verify_tls12_signature, rustls::crypto::verify_tls13_signature and $PROVIDER.signature_verification_algorithms.supported_schemes(), using the crypto provider of your choice.
• Rework certificate auth verifiers construction into a builder. This covers both server and client certificate verifiers: call WebPkiServerVerifier::builder() and WebPkiClientVerifier::builder().
