Crate totp_rfc6238

This library is for generating Time-based One-time Password (TOTP) codes/tokens, which is defined in RFC 6238.

Features of this crate:

• Both low-level and high-level APIs are provided.
• The length of the codes, the initial counter time (T0), update time interval (period) and hash algorithm are configurable.
• HMAC algorithms are implemented by ring.
• Read or write “Key Uri Format” (URIs start with otpauth://totp/) (the oathuri feature gate).
• Read or write key from base32-encoded string (the oathuri feature gate).

Note: This implementation does NOT consider the time earlier than the Unix epoch (1970-01-01T00:00:00Z).

See high_level::TotpGenerator for an example.
