Cryptographic algorithms for encryption, digital signatures, key agreement, authentication, and hashing. AES, Chacha20, ED25519, X25519, and more. Web Crypto support.

More...

1.0.4 #

  • Internal refactoring. Splits a number of large source files (such as Web Cryptography support) into more readable smaller files.
  • Adds VM implementation stubs for algorithms that are only supported in the browser (e.g. ecdhP256). The methods throw UnimplementedError in VM.
  • Improves Poly1305 performance.
  • Adds a few more tests.
  • Improves documentation.

1.0.3 #

  • Improves documentation.

1.0.2 #

  • Implements automatic use of Web Cryptography API when SHA1 or SHA2 is used in browsers. SHA2-512 becomes up to 100 times faster in browsers. ED25519 becomes approximately 30 times faster in browsers with the improved SHA512.
  • Better documentation and benchmarks.

1.0.1 #

  • Implements ed25519.newKeyPairFromSeed(seed).
  • Significantly improves ED25519 performance.
  • Small fixes in documentation.

1.0.0 #

  • A stable API.

0.3.6 #

  • Documentation fixes.

0.3.5 #

  • Adds XChaCha20 cipher.
  • When authenticated ciphers encounter incorrect MACs, they now throw MacValidationException (instead of returning null, which developers may ignore in some situations).

0.3.4 #

  • Fixes a cipher.name issue and improves documentation.

0.3.3 #

  • Improves documentation.
  • Improves outputs of cipher.name.

0.3.2 #

  • Improves documentation.

0.3.1 #

  • Improves documentation.
  • Eliminates AES-CBC and AES-CTR dependencies.

0.3.0 #

  • Breaking changes: Removes separate key generator classes. Many API changes designed to reduce chances of developers using the API incorrectly.
  • Adds HKDF and ED25519 support.
  • Adds more assertions and tests.
  • Improves documentation.

0.2.6 #

  • Fixed an issue with dependency constraints that conflict with Flutter SDK.
  • PrivateKey / SecretKey property bytes is deprecated and replaced with extract() and extractSync() to better support implementations that protect the underlying bytes such as Web Cryptography API.
  • Improves documentation.

0.2.5 #

  • Adds AES for non-browser platforms.
  • Fixes various bugs and improves test coverage.

0.2.4 #

  • Improves documentation.

0.2.3 #

  • Improves documentation, clarity, test coverage.

0.2.2 #

  • Improves documentation.
  • Deprecates ConstantTimeBytesEquality in favor of constantTimeBytesEquality.

0.2.1 #

  • Improves documentation and stops exporting a few declarations.

0.2.0 #

  • Major refactoring and breaking API changes.
  • Improves in documentation.
  • Adds AES, P256/P384/P521, SHA1, Poly1305, and AEAD_Chacha20_Poly1305.

0.1.2 #

  • Improved documentation

0.1.1 #

  • Fixed example

0.1.0 #

  • Initial version
