Fixed

• 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.

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.

Added

• Support and tests for TOTP with SHA256 and SHA512

Fixed

• Crystal 0.28.0 changed the first argument for OpenSSL::HMAC#digest from a symbol to a type of OpenSSL::Algorithm. Updated this within the library thanks to @Xosmond.
