Seald SDK for Flutter: simple end-to-end encryption for your app

0.10.0 : 2025/09/08

• [new feature] Implement Anonymous SDK.
• [new feature] Anonymous SDK now can create AnonymousEncryptionSession. This session exposes six functions: EncryptMessage, DecryptMessage, EncryptFile, DecryptFile, EncryptFileFromPath, DecryptFileFromPath.
• [new feature] Implement serialization / deserialization of EncryptionSession and AnonymousEncryptionSession.
• [breaking change] The internal codes for representing RetrievalDetails flows have changed to align with JS, so the RetrievalDetails of some sessions that were cached before update and retrieved from cache after update may be invalid.
• [new feature] Add functions EncryptionSession.ListRecipients to list all recipients of an EncryptionSession
• [breaking change] session.RevokeRecipients can now revoke SymEncKeys & TMR Accesses, and takes the corresponding arguments.

0.9.0 : 2025/02/05

• [enhancement] Encryption / Decryption from file paths now streams the data in chunks, to avoid having to load the entire file in-memory, and for better performance.
• [new feature] Add optional metadata argument to createEncryptionSession, to be able to add an arbitrary metadata string.
• [new feature] Add sealdSdkVersion to get the current SDK version.
• [enhancement] Update dependencies

0.8.0 : 2024/11/20

• [breaking change] Correctly specify minimum Flutter version as 3.10.0. Version 0.7.0 was already incompatible with Flutter versions older than 3.10.0, it just was not specified in pubspec.yaml.
• [new feature] Add group TMR temporary keys functions to join a group using TMR. CreateGroupTMRTemporaryKey, ListGroupTMRTemporaryKeys,DeleteGroupTMRTemporaryKey, ConvertGroupTMRTemporaryKey and SearchGroupTMRTemporaryKeys.
• [enhancement] Update dependencies

0.7.1 : 2024/09/12

• [bug fix] Fix sending of SDK version header
• [bug fix] Now respects configured keySize when using native key generation.
• [bug fix] Fix memory-management of session.encryptFile and session.decryptFile, and their async versions.
• [enhancement] First release publicly available on GitHub

0.6.0 : 2024/05/30

• [enhancement] Better performance when retrieving the same session multiple times in parallel when cache is enabled: now only one calls hits the API, while the others wait for it then use the cache.
• [enhancement] Add default rights when handling recipients.
• [new feature] In SSKS Password, SaveIdentityFromPassword, SaveIdentityFromRawKeys, and ChangeIdentityPassword now return the SSKS ID of the stored identity, which can be used by your backend to manage it.
• [new feature] In SSKS TMR, adding new SaveIdentityResponse class, which is returned by SaveIdentity.
• [breaking change] In SSKS TMR, challenge is now a proper optional argument for all methods. This changes the order of arguments.
• [breaking change] Change String databaseEncryptionKeyB64 argument of SealdSDK constructor to Uint8List? databaseEncryptionKey.
• [new feature] Add sealdSdk.retrieveMultipleEncryption() method, which takes an array of session IDs as input, and returns an array of EncryptionSession instances.
• [new feature] Add sealdSdk.prepareRenew() method, which return a prepared key renewal that can be stored on SSKS to avoid any data loss situation during a private key renewal, and add the corresponding preparedRenewal argument in method renewKeys.
• [enhancement] Send public key hash at login for better performance.
• [new feature] Also add privateKeys argument to methods addGroupMembers / removeGroupMembers, and to all async methods.
• @flutter [breaking change] Rename generatePrivateKeys to generatePrivateKeysAsync.
• @flutter [breaking change] Order of some optional args has changed, for coherence with other languages.

• [breaking change] SealdSdk must now be instantiated from the root isolate, or you must pass the rootIsolateToken argument.
• [new feature] Add the possibility to create TMR access to retrieve encryptionSession. Add convertTmrAccesses that can convert TMR accesses to classic access for a recipient.

0.4.0-beta.2 : 2024/01/05
