Changelog

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.13.0] - 2023-09-06

Changed

• Conditions should not be optional as it pertains to AuthenticatedData and AccessControlPolicy types since conditions-based decryption (CBD) requires conditions. (#80)

0.12.0 - 2023-08-28

Changed

• Modified ThresholdDecryptionRequest to use CiphertextHeader and AccessControlPolicy to utilize encapsulation now provided by ferveo. (#74)

Added

• Added ThresholdMessageKit which is the representation of data encrypted via ferveo that utilizes data encapsulation and an ephemeral symmetric key. (#74)
• Added AccessControlPolicy which contains access metadata (conditions, public key, authorization, etc.) that forms part of the ThresholdMessageKit. (#74)
• Added AuthenticatedData which forms part of the AccessControlPolicy and is needed to ensure that the aad is consistent during the encryption process and during the decryption process. (#74)
• Added encrypt_for_dkg method for generation of ferveo Ciphertext and AuthenticatedData. (#74)

0.4.1 - 2022-10-22

Fixed

• Finish up introducing the Address type in the spots forgotten in #34. Namely, in Python bindings: in TreasureMap.destinations(), in RetrievalKit.queried_addresses(), and in NodeMetadata.staking_provider_address(). (#38)

0.4.0 - 2022-10-02

Changed

• Conditions and context are now strings instead of bytestrings. (#33)
• Methods taking VerifiedCapsuleFrag objects use "vcfrag" instead of "cfrag" for their names and the names of the corresponding parameters. (#33)
• Use a workaround with wasm-bindgen-derive to support Option<&T> and Vec<&T> arguments, and Vec<T> and tuple return values, with correct TypeScript annotations. Removed all the Builder pattern helper classes. (#34)
• Use Address instead of plain bytes in arguments and return values (both in WASM and Python bindgins). Export the Address type. (#34)
• umbral-pre dependency bumped to 0.7. (#36)
• ReencryptionResponse::new() now takes an iterator of pairs (Capsule, VerifiedCapsuleFrag) instead of two separate iterators; bindings changed correspondingly. (#37)
• Change Iterable to Sequence in Python binding type stubs: bindings cannot actually take just iterables. (#37)
• AuthorizedKeyFrag.verify(), ReencryptionResponse.verify(), and AuthorizedTreasureMap.verify() now consume self. (#37)

Added

• conditions getters in MessageKit and RetrievalKit in WASM bindings. (#32)
• Attributes MessageKit.conditions, ReencryptionRequest.conditions, and ReencryptionRequest.context in Python typing stubs. (#32)
• Conditions and Context newtypes, to be used instead of raw objects. (#33)
• MessageKit, RetrievalKit, and ReencryptionRequest protocol versions bumped to v1.1. (#33)

Fixed

• Removed serde dependency for WASM bindings. (#34)

0.4.0-alpha.0 - 2022-09-07

• Fixed the type annotation for signer in generate_kfrags() in Python type stubs. (#28)

Added

• conditions and context to ReencryptionRequest with python/wasm bindings to expose them. (#26)
• conditions to MessageKit and RetrievalKit with python/wasm bindings to expose them. (#26)
• Rust-native tests for these new attributes and getters. (#26)

0.3.0 - 2022-08-16

Changed

• Bumped umbral-pre to 0.6, and the nested dependencies accordingly. (#17)
• Following the changes in umbral-pre 0.6, the types that were serde-serialized in human readable formats as hex will now have a "0x" prefix. (#17)

Added

• Eq marker for HRAC and FleetStateChecksum. (#17)
• Python typing stubs. (#20)
• The Python module nucypher_core.umbral now exports KeyFrag. (#20)
• Display impl for HRAC and FleetStateChecksum, and exposed it in the Python and WASM bindings. (#22)

0.2.0 - 2022-04-24

Changed

• Changed from sha3_256 to Keccak when building FleetState and HRAC. (#15)

0.1.1 - 2022-03-15

Fixed

• umbral-pre bumped to 0.5.2 and k256 bumped to 0.10.4 to make use of an important bugfix (see RustCrypto/elliptic-curves#529). Previous 0.1.* versions (using k256 0.10.2 with the bug) are yanked.

0.1.0 - 2022-03-14

Changed

• Renamed staker_address to staking_provider_address in NodeMetadataPayload fields and RevocationOrder::new parameters. (#10)
• Renamed NodeMetadataPayload.decentralized_identity_evidence to operator_signature. (#10)
• Declared NodeMetadataPayload.operator_signature as recoverable::Signature instead of just a byte array. This allows the user to detect an invalid signature on NodeMetadata creation. (#11)
• Renamed NodeMetadataPayload.certificate_bytes to certificate_der (although it is not deserialized on the Rust side, so the DER format is not strictly enforced). (#13)
• Changed some method and field names in WASM bindings to conform to JS style (camel case). New names are: TreasureMap.publisherVerifyingKey, TreasureMap.bobVerifyingKey, TreasureMap.encryptedKfrag, RetrievalKit.queriedAddresses, RevocationOrder.verifySignature, NodeMetadataPayload.verifyingKey, NodeMetadataPayload.encryptingKey, NodeMetadataPayload.timestampEpoch, MetadataRequest.announceNodes. (#9)
• Moved ADDRESS_SIZE to Address::SIZE. (#14)
• MetadataResponse::verify() and ReencryptionResponse::verify() return a Result instead of Option. (#14)
• Renamed RevocationOrder::verify_signature() to verify() and made it return a Result<(Address, EncryptedKeyFrag)>. (#14)

Added

• TreasureMap::make_revocation_orders() (with the corresponding methods in Python and WASM bindings). (#9)
• HRAC.fromBytes() in WASM bindings (#9), and in Python bindings (#14).
• RevocationOrder.stakingProviderAddress in WASM bindings. (#9)
• MetadataResponse.verify() in WASM bindings. (#9)
• impl From<[u8; 16]> for HRAC. (#9)
• Made RevocationOrder.staking_provider_address public. (#9) Rolled back in (#14) in favor of the return value from verify().
• HRAC::SIZE constant (#14)
• VerificationError for use in various verify() methods. (#14)

Fixed

• Some methods in WASM bindings that were previously taking self are now taking &self, leading to a more idiomatic behavior in JS. (#9)

0.0.4 - 2022-02-09

Changed

• Changed "worker" to "operator" in the API, according to the new terminology. (#5)

0.0.3 - 2022-02-03

Fixed

• Added the manifest to the Python bindings package, fixing the source distribution build.

0.0.2 - 2022-01-25

Changed

• umbral-pre dependency bumped to 0.5 (and to match it, MSRV to 1.56, and Rust edition to 2021). The API was updated accordingly (mainly due to the no-clone approach). Note that this changes the ABI as well. (#4)
• NodeMetadataPayload.decentralized_identity_evidence is now a fixed-sized array in the serialized metadata. (#2)
• k256 dependency bumped to 0.10, and umbral-pre to 0.5. (#2)
• NodeMetadataPayload.canonical_address and the parameter ursula_address of RevocationOrder::new() are renamed to staker_address. (#2)

Added

• WASM bindings. (#1)
• NodeMetadataPayload::derive_worker_address() method. (#2)

0.0.1 - 2021-12-25

Initial release.
