otp

v3.2.0

• Update timezone to 0.10.0 (Thanks @NM4ik)
• Some minor cleanup for how long this repo has been untouched

What's Changed

• Update timezone package in pubspec.yaml from ^0.9.0 to ^0.10.0 by @NM4ik in #52

New Contributors

• @NM4ik made their first contribution in #52

Full Changelog: 3.1.4...3.2.0

• Update timezone to 0.10.0 (Thanks @NiM4iK)
• Some minor cleanup

What's Changed

• Allow lowercase base32 strings if isGoogle is set to true by @amadejkastelic in #46

Full Changelog: v3.1.2...3.1.4

• Fix case issues when using isGoogle:true (Thanks @amadejkastelic)

Fix incorrect padding logic

• Fix incorrect padding logic for isGoogle HOTP

• Allow isGoogle flag for HOTP

• Loosen version constraint on the crypto so that there is no conflict between our library and those requiring 3.0.1 or 3.0.0. crypto versions 3.0.1 and 3.0.2 don't affect this library or are just doc/link fixes.

• Bug where all secrets were being treated as Base32 by default, when RFC default is ASCII. Base32 is only when using Google Authenticator mode. This came about due to even when not using Google, secrets were Base32 encoded anyway by most implementations, so the bug wasn't caught, including my tests where I pre-encoded everything as Base32. (thanks @pt-rick for catching this.)
  • Used notp and otplib to verify my outputs.

• Partially change behavior, if it is invalid Base32, it should throw, but in certain cases, it still doesn't throw, so we do fallback behavior.

• Fix when secrets are not Base32 causing infinite loops because the resulting list is size 0.
• Don't assume Base32, use the secret as is if not base32.

• Add remainingSeconds() in order to calculate the remaining seconds based on lastUsedTime. (thanks @AkbarAsghari)

• Add lastUsedTime and lastUsedCounter to provide additional information for users and potential debugging points.

• Docs and file cleanup

• Nullsafety conversion

• Improve pub package score (thanks @DavBfr)
• Use const and final instead of var (thanks @DavBfr)
• Document public API members (thanks @DavBfr)

• Update quick_log to latest version

• Correctly use Google Auth flag (isGoogle) to disable padding. (thanks hpoul)

• Add Google Auth flag, because they do SHA1 TOTP without Padding the secret.
• Reverting _int2bytes function back to old implementation, as the new on uses int64 which breaks flutter web and dart2js as it doesn't have support for Int64.

• Fix secret paddding to follow proper TOTP secret padding and sizing for SHA256, SHA512
• Remove RFC unsupported hashes. SHA224 and SHA384 are no longer supported.
• Show warning when using anything other than SHA1, as the RFC doesn't support it so I have found that libraries don't pad correctly for HOTP.
• At the same time, SHA1 is now again the HOTP default.
• Add optional TOTP style paddding for HOTP when using SHA256 and SHA512.
• Force version 1.1.1 of Base32 library, as that was a major bug fix release that improved Base32 support.
• Add documentation and additional information on how to use this library.

• Fix type error at runtime for RandomSecret generation. MR #14 (thanks readytopark)

• Switch to crypto lib inplace of PointyCastle for HMAC

• Formatting
• No changes from rc1, accepting the 1-3 second timing difference between constant time code checks until someone can help me figure out how to make it match.

• Switched to PointyCastle for crypto and support for more than SHA1 hashing for tokens (amadejkastelic)

• Add new TOTP interval parameters (optional)

• Cleanup and remove dead code

• Dart 2.0 updates

• Dart 1.0 Readiness

• Fixing crypto library.

• Fixing language changes.

• No functionality changes, just fixing a bad file state it git and in the package involving the case of the file.

• Initial Documented Release
