Allow setting setUserAuthenticationValidityDurationSeconds

[pesonsita]

Hello,

I want to know if its possible to set setUserAuthenticationRequired and setUserAuthenticationValidityDurationSeconds from the dependence. From that what I can see, I don't have the possibility to set this, is that right? If yes, how??

Thanks in advance

setUserAuthenticationRequired is set by default for all Ciphers used for encryption/decryption in RxFingerprint (both AES and RSA). It is indeed not possible to provide a value for setUserAuthenticationValidityDurationSeconds at the moment. However I'm currently thinking about a refactor to enhance the public API of RxFingerprint to open up more customization to the users of RxFingerprint. I'll take setUserAuthenticationValidityDurationSeconds into account for that as well.

Thanks for your quickly answer. It would be nice to have more customization possibilities. Nice API 👍

Thank you

I would be interested in having the authentication validation duration set. In my case, once I authenticate the user, I present the user account selection (user credentials saved) to be able to retrieve encrypted credentials. With current limitations, I need to present user twice with fingerprint sensor. First for prior to account selection and second time when retrieving the credentials.

This would be a great addition to RxFingerprint. To not further add more overloaded methods to RxFingerprint for encryption/decryption I think this would be a great configuration to have in the Builder pattern I started working on in #72. Then the builder could take an additional method: builder. setUserAuthenticationValidityDurationSeconds(duration) to set this up and use this value for all encryption/decryption operations.
