otp 3.0.0-nullsafety.0

RFC6238 Time-Based One-Time Password / Google Authenticator Library

Changelog

v3.0.0-nullsafety.0

• Nullsafety conversion

v2.2.3

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

v2.2.2

• Update quick_log to latest version

v2.2.1

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

v2.2.0

• 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.

v2.1.0

• 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.

v2.0.3

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

v2.0.2

• Switch to crypto lib inplace of PointyCastle for HMAC

v2.0.1, v2.0.0

• 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.

v2.0.0-rc1

• BREAKING CHANGE Switched default hashing algorithm to SHA256 from SHA1
• Add constant time verification function to avoid timing attacks on code comparison.
• Add String return variant of code generation.

v1.0.3

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

v1.0.2

• Add new TOTP interval parameters (optional)

v1.0.1

• Cleanup and remove dead code

v1.0.0
