QUESTION
As there are hashing differences for identity user passwords we need to keep old users without forcing them to renew their passwords. So I have to change hashing to old style. I am following this answer https://stackoverflow.com/a/57074910/1651298 but new hasher is not being used despite of the fact that PasswordHasher
is replaced in service container.
Steps to reproduce the issue:
Create ASP Core MVC
project for .NET 6
and choose Individual Accounts
for authentication. Change Program.cs
file:
ANSWER
Answered 2022-Apr-05 at 08:48In one of my projects, I migrated existing users (with my own custom tables) into a .NET 6 project with .NET Core Identity. In the DataContext, I extended my user table by a legacy hash column from my old application.
Whenever a user tries to log in (with email + password), I check if there is still a value in the legacy hash column. If that is the case,
- I calculate the old hash based on the old mechanism and see if they match
- If they match, I use .NET Core Identity to set the new password (based on what the user entered. The user doesn't know that I changed the underlying hash algorithm). I do this by creating a PasswordResetToken and then using the ResetPassword functionality.
- Afterwards, I remove the legacy hash from the user row.
In your case, just set up .NET Core identity the way it should work for new users. Take care of migrating existing passwords during the login method.
QUESTION
I'm trying to figure out why Apple's Natural Language API returns unexpected results.
What am I doing wrong? Is it a grammar issue?
I have the following four strings, and I want to extract each word's "stem form."
...ANSWER
Answered 2022-Apr-01 at 20:30As for why the tagger doesn't find "accredit" from "accreditation", this is because the scheme .lemma
finds the lemma of words, not actually the stems. See the difference between stem and lemma on Wikipedia.
The stem is the part of the word that never changes even when morphologically inflected; a lemma is the base form of the word. For example, from "produced", the lemma is "produce", but the stem is "produc-". This is because there are words such as production and producing In linguistic analysis, the stem is defined more generally as the analyzed base form from which all inflected forms can be formed.
The documentation uses the word "stem", but I do think that the lemma is what is intended here, and getting "accreditation" is the expected behaviour. See the Usage section of the Wikipedia article for "Word stem" for more info. The lemma is the dictionary form of a word, and "accreditation" has a dictionary entry, whereas something like "accredited" doesn't. Whatever you call these things, the point is that there are two distinct concepts, and the tagger gets you one of them, but you are expecting the other one.
As for why the order of the words matters, this is because the tagger tries to analyse your words as "natural language", rather than each one individually. Naturally, word order matters. If you use .lexicalClass
, you'll see that it thinks the third word in text2
is an adjective, which explains why it doesn't think its dictionary form is "accredit", because adjectives don't conjugate like that. Note that accredited is an adjective in the dictionary. So "is it a grammar issue?" Exactly.

QUESTION
Good evening everybody. I have a problem with sha256 Hash.
I have this example string from the amazon pages:
...ANSWER
Answered 2022-Mar-08 at 20:58At first I couldn't reproduce this behavior by copy-pasting your code. Then I pasted it into an editor configured to save all linebreaks as CRLF
- at which point I also got B51325A14138B31939381CB391819CE8A5F09DEEA778721C4360F0DAC1FAB79C
.
So the likely explanation is that you wrote your script in an editor that saves all files with Windows-style line breaks.
You can work around this by replacing all Windows style linebreaks in the resulting string value with a single newline character at runtime:

i have been trying to follow these guide to learn NX, but i encounter this problem when i tried to serve the nestJs api you can see the complete code on this repo
...ANSWER
Answered 2022-Mar-05 at 12:48I use NX everyday on a mac with M1 chip and i never had such problems.
I think you should better use the last version of NX available with this tutorial on the NX website : NestJS with NX

I have an enum with associated values, which I want to use as an item in RxDataSources. I tried conforming it to identifiable by conforming it to Hashable like below
...ANSWER
Answered 2022-Mar-01 at 15:14You have confused Identifiable
, a Swift built-in protocol, with IdentifiableType
, a protocol in the RxDataSource library.
You can just conform to IdentifiableType

QUESTION
I am attempting to place an object (a view of a square) on the screen and then drag it immediately. What I have achieved is the following:
- I can drag existing objects that are already on the screen.
- I can place new objects on the screen, but they do not drag along immediately. I need to lift my finger, and then tap on them again in order to drag.
How can I achieve the functionality: Place object on screen and immediately start dragging? I am missing something here. My code:
ContentView with square placement logic:
...ANSWER
Answered 2022-Jan-30 at 12:35A possible approach is to handle drag and creation in "area" (background container), while "item" views are just rendered at the place where needed.
Find below a simplified demo (used Xcode 13.2 / iOS 15.2), see also comments in code snapshot.
Note: tap detection in already "existed" item is an exercise for you.

I tried to run the fixture below on Symfony 5 using the command php bin/console d:f:l
.
I get this error: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'contact_email' cannot be null
The same code logic is working fine for Post entities when creating them manually through the CRUD. Are fixtures not compatible with subscribers (events) or did i make a mistake?
Thank you.

QUESTION
Apologies if the title is confusing. So, I'm implementing a chat app where there's a list of ChatRow
s that would, upon clicking, entering into a MessageView
. When a user sends a message, the list of ChatRow
s may reorder because I order them in a way such that ones contain the latest messages are placed on the top.
The code looks roughly like this (let me know if more detail is needed):
...ANSWER
Answered 2022-Jan-11 at 23:26You're correct that this relates to the fact that the List
lazily loads elements -- once the NavigationLink
is off the screen, if the Chat
element changes, the View
ends up getting popped off the stack.
The standard solution to this is to add a hidden NavigationLink
to your hierarchy that has an isActive
property that controls whether or not it is active or not. Unfortunately, it requires a little more boilerplate code than the convenient list element binding that was introduced in Swift 5.5.
Your code might look something like this:
QUESTION
I have following code in node.js using crypto-js to encrypt password using AES with Secret Key and IV.
...ANSWER
Answered 2022-Jan-07 at 19:19In the CryptoJS code, the second parameter in crypto.AES.encrypt()
is passed as a string, so it is interpreted as passphrase.
Therefore, during encryption, an eight bytes salt is first created and from this, along with the passphrase, key and IV are derived using the KDF EVP_BytesToKey()
.
The IV derived with createRandomIv()
and explicitly passed in crypto.AES.encrypt()
is ignored!
hash.ToString(
) returns the result in OpenSSL format consisting of the prefix Salted__ followed by the salt and by the actual ciphertext, all Base64 encoded. eHex
contains the same data, but hex instead of Base64 encoded.
CryptoJS does not automatically disable padding for stream cipher modes like CTR, so the data is padded with PKCS#7, although this would not be necessary for CTR.
In the Go code, the IV that is not required must first be removed. From the remaining data, salt and ciphertext are determined.
From salt and passphrase, key and IV can be retrieved with evp.BytesToKeyAES256CBCMD5()
.
With key and IV the decryption with AES-CTR can be performed.
Finally, the PKCS#7 padding must be removed.
The following Go code implements these steps. The input data was generated with the NodeJS code:
