[0.5.0] - 2019-10-09

Crystal 0.31.0 changed the behaviour of Int#/ in favour of Int#// for integer division. This affected the base32 module, which no longer builds. Updated to point at a fork of base32 that does build in 0.31.0.

[0.4.0] - 2019-08-18

Changed

Crystal 0.30.0 deprecated URI.escape in favour of URI.encode_www_form. Updated this to match the original behaviour (with space_to_plus: false).
Crystal 0.28.0 deprecated Time.now. Updated to use Time.utc which is actually more correct according to the RFC.
Crystal 0.29.0 deprecated the behaviour of Int#/ to return integers. Changed to use Int#// instead.

[0.3.0] - 2019-07-27

Added

Support and tests for TOTP with SHA256 and SHA512

Fixed

Fixed

[0.1.3] - 2018-05-27

Added

Added authenticator_uri to HOTP and TOTP objects to generate URIs for 2FA authenticator apps.

[0.1.2] - 2018-05-26

Added

Added an allowed_drift to verify methods so that codes can be valid longer.
