QUESTION
I am working on a wordle bot and I am trying to match words using regex. I am stuck at a problem where I need to look for specific permutations of a given word.
For example, if the word is "steal" these are all the permutations: 'tesla', 'stale', 'steal', 'taels', 'leats', 'setal', 'tales', 'slate', 'teals', 'stela', 'least', 'salet'.
I had some trouble creating a regex for this, but eventually stumbled on positive lookaheads which solved the issue. regex -
'(?=.*[s])(?=.*[l])(?=.*[a])(?=.*[t])(?=.*[e])'
But, if we are looking for specific permutations, how do we go about it?
For example words that look like 's[lt]a[lt]e'. The matching words are 'steal', 'stale', 'state'. But I want to limit the count of l and t in the matched word, which means the output should be 'steal' & 'stale'. 1 obvious solution is this regex r'slate|stale', but this is not a general solution. I am trying to arrive at a general solution for any scenario and the use of positive lookahead above seemed like a starting point. But I am unable to arrive at a solution.
Do we combine positive lookaheads with normal regex?

Answered 2022-Mar-23 at 11:00I had the same issue after restarting my PC.
try any of the following:
upgrade your dependencies in your pubspec.yaml
or
try flutter flutter clean then flutter run
lastly, if it didn't work you've to delete the flutter src folder in
Script 'C:\src\flutter and reinstall it again
make sure the path you created your flutter project have no spaces.
QUESTION
I want to create a GUI in C# that will be used to run keytool on cmd.exe behind the scenes to create a keystore, including a key, and certificate data.
Input data then requires
- Keystore path
- Password
- Key alias
- Key password
- Validity
- Certificate info (cn, ou, o, l, st and c)
Unfortunately people may type special characters in their passwords and also space is allowed in the certificate info.
Overall I am worried someone may input some information somewhere that can result in a disastrous command running behind the scenes once this is called (like rm -rf *).
Is there a way to pass a java properties file with the input information to keytool or is there any way that I can safely escape all the data that is passed as string parameters to keytool?
I could not find any type of file that keytool could take, even in separate steps, that would eliminate this issue.
here's the unsafe code (warning: IT'S UNSAFE!!):
...ANSWER
Answered 2022-Feb-18 at 23:39I believe that invoking the keytool binary directly instead of cmd.exe would do the trick if you don't want the user to inject shell commands.
QUESTION
I want to discuss wether good or bad idea:
I got a MySQL DB and created a common table "user" to authenticate an login.
...ANSWER
Answered 2022-Feb-11 at 14:25The primary weakness is that you pass the password in plaintext when you create the row, and every time you call your checkUserAuth() function.
This can be wiretapped (unless you ensure using SSL connections between app and database) and it will be written to the query log if you have the query log enabled. It's also visible in the processlist and the performance_schema statements history tables.
This is a good reason to do the hashing in the client, and send only the salted hash of the password when you create the row. When you authenticate, fetch the salted hash from the database, and validate it against user input in the client.
QUESTION
I understand the Oauth code flow which involves the mobile app, app server, auth server, resource server. The app server is registered with auth server using the clientidand secret. The idea being that mobile app calls an endpoint of the app server which triggers the code flow eventually resulting in callback from the auth server to the app server with the auth code. The app server presents the secret and code to auth server to get the access token.
The other legacy option where there is no clientid and secret is the implicit flow wherein the mobile app receives the redirect url with the auth code (assuming redirect url destination is a SPA) which will invoke auth server endpoint to get the access token.
This is insecure because anyone can steal the access code from the url.
The solution to this for clients like mobile app is to use pkce. A random number hash is sent in the initial request which is verified later on when the auth code is passed to retrieve the access token.
This prevents the compromise of the access code from the url if an attacker is snooping because without initial hash the auth code is useless.
However how can the situation where the mobile phone is hacked and the secret and auth code is recorded by an attacker be handled to prevent misuse?
...ANSWER
Answered 2022-Feb-07 at 13:59These are the standard options:
PKCE uses a different code_verifier and code_challenge for every login attempt. If an authorization code is somehow captured from the system browser by an attacker it cannot be exhanged for tokens. No client secret is used, since a mobile app is a public client.
Use HTTPS redirect URIs (based on mobile deep links) so that if an attacker steals your client_id and redirect_uri they cannot receive the response containing the authorization code and will not be able to get tokens.
See this previous answer of mine for some further details, though claimed HTTPS schemes are tricky to implement.
Of course if an attacker has full control over a device, including authentication factors such as autofilled passwords, there may still be attack vectors
QUESTION
I was reading this: https://docs.microsoft.com/en-us/windows/win32/seccrypto/example-c-program-using-cryptprotectdata
I was wondering about this method. Does this only store it in the process memory while the process is running? If so, is there a persistent data storage that the win32 api provides that's secure and does not create any files on the filesystem? Some sort of keychain/keyvalue store that's secure?
My intention here is to secure a secure login token that can be used for two weeks by a program I am writing for the user to login. I don't think this data should be stored in a file that is accessible by anyone. If someone were to find out about the file, they could steal the file and login with someone else's account as long as the token is valid. Environment variables and the windows registry are also not acceptable solutions. This needs to be inaccessible by the user.
...ANSWER
Answered 2022-Feb-05 at 23:46There's nothing wrong with storing your login token in a file (or in the registry, which I personally would prefer) provided that you encrypt it properly. The documentation for CryptProtectData has this to say:
Typically, only a user with the same logon credential as the user who encrypted the data can decrypt the data. In addition, the encryption and decryption usually must be done on the same computer.
So you're already halfway there. Only the user (and machine) that 'own' the token can decrypt it.
In addition to that, there is this parameter:
[in, optional] pOptionalEntropy
A pointer to a DATA_BLOB structure that contains a password or other additional entropy used to encrypt the data. The [same] DATA_BLOB structure used in the encryption phase must also be used in the decryption phase
So this should be something known only to your program (a GUID would be the obvious choice). Then, only that program can decrypt - and hence use - the token.
You might take some steps in your code to obfuscate this, such as storing it in some mangled form and only demangling it just before you use it. Then call SecureZeroMemory when you're done with it to make life harder for potential snoopers.
QUESTION
I am new to the OAuth world and I am trying to understand the benefits of using PKCE over traditional Authorization code grant. (Many of my assumptions could be wrong, so I would thank for your corrections.)
I am a mobile app developer and according to OAuth documentation, client secrets can't be hardcoded in public clients' app code. The reason to avoid hardcoding the client secret is that a hacker could decompile my app and get my client secret.
The hacker with my client secret and my redirect_url, could develop a fake application. If a final user (User1) downloads the real application and the hacker's application (both), the fake application could listen to the real application callback and get the authorization code from it. With the authorization code (from the callback) and the client secret (stolen by decompiling my app), the hacker could get the authorization token and the refresh token and be able to get for example User1's data.
If other users download the real and the fake application, their data would also be in danger. Am I right? Would the hacker need both or could he/she do an attack only with the authorization code? Does the fifth step of the image requires the client secret and authorization code?
The attack is called interception attack.
To solve the the problem of hardcoding client secrets in the public client app and make it impossible for hackers to get the client secret and steal tokens, PKCE was invented. With PKCE, the client app code doesn't need to have the client secret hardcoded as PKCE doesn't need that information to get the tokens of the final users.
The PKCE flow creates a random string, transforms it to a SHA-256 hash value and to Base64. In the second point of the image, that encoded string is sent to the authentication server with the client id. Then the authorization code is sent in the callback and if any malicious app intercepts the code, it wouldn't be able to get the tokens as the fifth point of the image needs the original random string that was created by the legitimate app.
That is great, but if the client secret isn't need any more to get the tokens to access User1 data, how can I avoid a hacker developing a fake app which use PKCE flow with my client id and getting the tokens of the users who think that app is the legitimate one?
As the fifth step of the image don't need any more the client secret to get the tokens, anyone could develop fake apps using my public client id, and if any user downloads the fake app and do the OAuth flow, the hacker could get its tokens and access that users data!
Am I right?

OAuth 2.0 or PKCE does not protect against "fake apps".
The PKCE does protect against having a malicious app on the device to steal a token that is intended for another app. E.g. think of a Bank app, it is not good if another app on the device can get the token that the Bank app is using. That is the case illustrated in your picture and that PKCE mitigates against.
As the 5th step of the image don't need anymore the client secret to get the tokens, anyone could develop fake apps using my public client id.
A mobile app cannot protect a client secret, similarly to JavaScript Single Page Applications. Therefore these clients are Public Clients rather than Confidential Clients according to OAuth 2.0. Only Confidential Clients can protect a client secret in a secure way, only those should use client secrets. PKCE is a good technique for Public Clients but might be used for Confidential Clients as well.
if any user downloads the fake app and do the oauth flow, the hacker could get it's tokens and access that users data!
Contact Apple Store or Google Play store for "fake apps", or use e.g. Anti-malware applications. That is the mitigations against "fake apps". PKCE only mitigates the case when another app on the same device try to steal the token that is issued for another app (e.g. a bank app).

QUESTION
First of all, this question can be a duplicate but the question doesnt have enough information to solve the problem.
I have two windows in my native Win32 application. The first is a layered window with WS_EX_NOACTIVATE extended style and the second is a normal window. I want the layered one to be non-activatable. The problem is that, when I have two window in the same application, the layered one which must be non-activatable, gets activated when switching between them. But there is no problem when switching between two external windows, one being not belong to my application. How can I solve this problem? Or Can I solve that? Is there anything I missed? The following is a minimal reproducable example (didn't include any error checking for minimality.) Thank you for taking time.
ANSWER
Answered 2021-Dec-21 at 18:32Although I still don't understand the cause of the problem, with the help of @IInspectable's guidance and documentation, I was able to prevent the window from being activated by processing the WM_MOUSEACTIVATE message. The updated window procedure is as follows.
