I can use the epa-encrypt-region function to encrypt an arbitrary region of text. To do so, I perform
the following steps:
I am an evil user, so I use visual selection to mark the region that I want to encrypt.
I invoke the function using M-x. After doing this, I am greeted by a prompt with the following content:
Select recipients for encryption.
If no one is selected, symmetric encryption will be performed.
- ‘m’ to mark a key on the line
- ‘u’ to unmark a key on the line
[Cancel][OK]
u 8EF108635D200BC9 John Doe <john.doe#mail.com>
I move my cursor to the [OK] text and press enter. At this point, I am asked to enter a "Passphrase for symmetric encryption".
I enter a passphrase and press enter. At this point, the selected region gets encrypted. I can later decrypt the region by selecting it, invoking epa-decrypt-region and entering my passphrase.
How can I avoid having to press the [OK] button and to manually enter a password. I would like to be able to encrypt arbitrary regions by just performing two steps:
Select the region using visual selection
Invoke a function to encrypt the region with pre-defined passphrase.
Later, I want to be able to decrypt the region by selecting it, invoking a function and entering a
passphrase.
Does anyone know how I could achieve the above?

I'm trying to change my Assigned Endpoint Key on a LUIS app from the Starter key to a Pay As You Go key that I have created. I'm doing this in the 'Publish App' section of the LUIS dashboard. I can select the new key, and click Save, but this doesn't seem to do anything. The dialog disappears, but the Starter Key is still the Assigned Endpoint Key. I can do this as many times as I like, but it just doesn't save.
Any ideas what I might be doing wrong?
You are probably using luis in a European region. You should use https://eu.luis.ai instead of https://luis.ai
I have a root in firebase like in the I am trying to enable user to delete an item on list. But user can give up his decision. When user give up this decision, I want to insert the deleted item again in the database. But, I want to insert with old firebase generated key, because I am using firebase push keys. Is that a bad practice. How firebase generate these keys? Does it checks every key on db and generate a new one? Is that any possibility, that key marked as removed and generated later for another item? Sorry for the language. It has been hard to express.
EDITED: I want to use the old key because, I am getting the data with orderByKey. I dont want to lose order.
How firebase generate these keys? Does it checks every key on db and generate a new one?
Whenever you use push on a Database Reference, a new data node is generated with a unique key that includes the server timestamp. These keys look like -KiGh_31GA20KabpZBfa.
Because of the timestamp, you can be sure that the given key will be unique, without having to check the other keys inside your database.
Is that any possibility, that key marked as removed and generated later for another item?
No, it is not possible that two keys will collide, regardless of wether one has been removed or not.
But, I want to insert with old firebase generated key, because I am using firebase push keys. Is that a bad practice
Unfortunately, you can't generate the same key twice by just using push. So, it is not possible to delete a node with a given key and then use push to insert it again at the same path with the same key, because push would generate a different and unique key.
Instead of this, if ordering by key is that important to you, and there's a possibility that a deleted node can be reinserted then I would recommend you to do one of the following :-
Either save the key on the client side when it's deleted from the database, and use it when you need to reinsert.
Or , maybe, have a "deleted-keys" path in your database and save the deleted keys there. Of course, with this approach, you'd need to store additional information to identify the data that the key corresponds to.
It all really depends on your use case.
Calling push() will generate a key for you.
If instead you use child(), you can determine they key/path yourself.
ref.child("yourvalue").setValue("setting custom key when pushing new data to firebase database");

If you use Wordpress's built in password reset service it will go something like this:
Click forgot password
Enter your email or username
Receive a link in your email inbox
Click the link
Fill out form
That link you click, will look something like this:
http://yourdomain/wp-login.php?action=rp&key=vqwwSPzf6OK6bUv42XPk&login=natelough
If you try to change the &login to another name, it will reject you.
So, somewhere that 'key' is being stored in some way, and compared.
Where is it stored in the database?
I did an export of the database and searched the db for that string. It returned no results.
So what gives?
That key is generated by hashing a random string. You can see how this key is generated in the WordPress developer reference.
To answer your specific question, when a key is generated it is stored in the users table in the user_activation_key column. Only the most recently generated key is stored (invalidating previous reset keys). The key is also removed from the database once it has been used.
If you are looking to send these keys programmatically, you can generate them when you need them using get_password_reset_key(). That function accepts a WP_User object as its argument.
Depending on what you are trying to accomplish, there may be a more "best practices" way to do it than accessing that function directly.
The password is stored as a hash of the login name and password. You will find it in the users table under user_pass as an incomprehensible string. If the login name is changed, the entered password hashed with the login name will not match the string found in the database where the password was hashed with the original login name.
I'm using Dexi.io to scrape some data that outputs to Google Drive as a CSV, that gets parsed (through a Google sheets script) and added to a Native sheet (all automatically).
I'd like to push my data (automatically) to a "database Visualizer" of some sort (using knack.com currently) that allows me to display the data (in Table format) with some options to filter, sort and dig deeper; all protected by login creds that I manage.
I tried using Zapier to automate the Google Sheets to Knack integration, but Knack only has an option to "Create New Records" through Zapier and not "Update Records". (Updating records exists as an API endpoint)
I need help proceeding as I'm not a developer and am starting to hit the limits of my capabilities.
Could someone please recommend a tool (that integrates with Sheets, updates data periodically and lets me control the domain and login creds) or the optimal way to proceed with this? (I'd gladly hire a freelancer to help me build this out optimally)
Some more, potentially relevant, info: Dexi.io can output through FTP, Drive, Box or Amazon S3 (remember, not a dev :$)
kintone is a "database Visualizer" similar to Knack, and they have actions to update records.
https://zapier.com/zapbook/kintone/
There are two options to update records as there are two ways in which the unique key can be defined.
Each record in kintone has a "Record ID" associated with it - this is an autonumber made by kintone. You can specify this as the key to update, in which case you would use the "Update Record By Record ID" action.
If you would prefer though to set your own unique key and use that as the key to update, you can define that unique key in your database (I guess the data you are scraping has its own ID for each record). In this case, you can place a "Text (single-line)" field in your database, open up the options and select "Prohibit duplicate values" which will make this field into a unique field - meaning that no two records can hold the same value.
Once you set that field up (and update your kintone App settings), you can select this field to be the unique key to update for the "Update Record By Update Key" Action (the "Update Key" in the action name is referring to the unique key that you just made).
And yes, kintone gives you control over login creds, and each login cred can have different view/add/edit permissions over each record you have in your app.
You can also set a custom subdomain name, but the domain name will have to be kintone.com i.e. you can have a https:/ /mycustomname.kintone.com sort of name.
Hope this helps.
In my project i am sending a mail to the user to create a user account. I want to enable that link for the first time he/she clicks the link. if he clicks the link for more than 2 times,then it should go to custom error page.how to do this?
This depends on how the link is generated.
For example: If your link contains a username as GET-parameter, then you could simply query your database if the username is already in use. I would advise against that, because the user can easily change that GET-Parameter
I would recommend this: Your link should contain a unique identifier, most likly a hash. This hash is stored somewhere, to garantee it's uniqueness, like in the usertable of your database (a column for the hash of the registration link). That might also come handy, because you could create new user rows and already prefill them with necessary information. You could use these information upon rendering to insert text into the textboxes
