miniotp

An otp crate that aims for correctness of implementation, while giving the same speed that one would expect.

Features:

• std - on by default; enables use of system time and/or allocations.
• alloc - off by default; enables use of the alloc crate where allocations are required.
• only-gauth - you only use google authenticator-valid codes. This disables some features, like setting the length, algorithm, period, or epoch. This is enabled by default.
• cstr - enables support for creating a code from a AsRef<CStr>; for easier compatibility with noria::DataType::Text(_), or other data bases.
• base32 - on by default; enables a set of functions related to taking an OTP secret as or into a string.
