HMAC-SHA256 Generator Tool

[wapenshaw]

What's the Problem?

Could we have under hash Generators the HMAC-SHA256/512 generator?

Solution/Idea

HMAC(Hash-based message authentication code) is a message authentication code that uses a cryptographic hash function such as SHA-256, SHA-512 and a secret key known as a cryptographic key. HMAC is more secure than any other authentication codes as it contains Hashing as well as MAC.

Its a simple tool previewed here https://www.devglan.com/online-tools/hmac-sha256-online

This proposal will allow developers to accomplish generating Hash-based message authentication code using a secret key

Ability to generate hash based on a secret key

I thought of this design: A simple text box for the secret key - if it's non-empty, then use HMAC variants (HMACMD5, HMACSHA1 etc), otherwise simply use regular hashing algorithms. I have a prototype in progress, I'll share screenshots in few days.

Here's the functional version that I could implement:

There are other designs which are also possible:

1. Separate Hashing page for HMAC entirely (this could be an overkill)
2. A toggle switch to enable/disable Secret key textbox

I'm using MacAlgorithmProvider currently for this feature. I also noticed that SHA 384 hash output is missing, I could add implement that as well but I'm not sure why it was not added on the Hash generator screen.

@L1nu5 I agree with both your points, separate page just for HMAC would be overkill, by default you can disable the HMAC toggle so that it wont confuse users already using this page extensively. Also the Input field for the secret key could be better off being a single line text box.

Also thanks for responding. :)

@wapenshaw No problem! Here's what it looks like now:

1. Normal mode

2. HMAC mode

Things still need to be done:

1. I'm still fairly new to WPF/UWP stuff, and was wondering where I could find icons and their hexadecimal codes. It seems that we are using FluentSystemIcons by looking at some other XAML files in the solution. I also looked at this repository for any information on hex codes for the icons but could not find much. Any directions on this are very much appreciated.

2. I'm currently using hardcoded strings for the toggle switch and the secret key textbox title. I'm pretty sure we would need localized versions of these two but we could also do this after we merge my PR.

I'm still waiting for any other design suggestions. If this version is the ideal one, I'll issue a PR.

@veler I couldn't see the latest version (Version 1.0.8.0 | X64 | RELEASE | db9b428 | db9b428) have this new feature. Is it published?
