Correct setting for algorithm

[sidlr]

Hello,

Thanks for that great plugin - i have been using it for a while and it always worked for me.

Now I should add a OTP with sha256 as algorithm, but can't find any documentation how to do it. According to the source code, sha1, sha256 and sha512 are supported, but e.g. in the setup dialog, there is no option for selecting the algorithm.

I know, that '30;6' in the TOTP Settings stands for 30s & 6 digit. Tried there various thing to set the algorithm to sha256, but sometimes the settings were wrong or the generated key was still done by sha1.

Is that even possible at the moment or have I just overlooked it?

Thanks for the help.

Are you talking about this line?

KeeTrayTOTP/KeeTrayTOTP/KeyUri.cs

Line 10 in e8f1de5

private static string[] ValidAlgorithms = new[] { "SHA1", "SHA256", "SHA512" };

That's a class for a future improvement of the code and doesn't represent the current support of the different hashing algorithms.

It looks like we only support sha1 atm:

KeeTrayTOTP/KeeTrayTOTP/Libraries/TOTPProvider.cs

Line 132 in 240f471

using (var hmac = new HMACSHA1(key, true))

But we would use your issue to track this improvement :)

Would be great - thanks!

@sidlr I found out that KeePass itself provides different algorithms for generating TOTP codes. Even the sha256
see here: https://keepass.info/help/base/placeholders.html#otp

@dannoe thanks for the tip! Got wrong codes for the credentials with sha256 at first, but with the latest version (4.48.1) it works.

you need to add an input field where you can select an algorithm
