I want to delete all stored passwords from SourceTree.
Is there any way to delete all the username and passwords ?

I have read the MongoDB's official guide on Expire Data from Collections by Setting TTL. I have set everything up and everything is running like clockwork.
One of the reasons why I have enabled the TTL is because one of the product's requirements is to auto-delete a specific collection. Well, the TLL handles it quite well. However, I have no idea if the data expiration will also persist on the MongoDB backups. The data is also supposed to be automatically deleted from the backups. In case the backups get leaked or restored, the expired data shouldn't be there.
Backup contains the data that was present in the database at the time of the backup.
Once a backup is made, it's just a bunch of data that sits somewhere without being touched. The documents that have been deleted since the backup was taken are still in the backup (arguably this is the point of the backup to begin with).
If you want to expire data from backups, the normal solution is to delete backups older than a certain age.
As mentioned by #D.SM data is not deleted from backup. One solution could be to encrypt your data, e.g. with Client-Side Field Level Encryption
For every day use a new encryption key for your data. When your data should expire, drop according encryption key from your password storage. With this your data becomes unusable, even if somebody restores the data from an old backup.
I'm trying to set up a Mail Server using Postfix and Dovecot.
I have my users stored in a PostgreSQL database with bcrypt hashed passwords.
After some researching, I found ways to read users from a PostgreSQL database, but with passwords stored in plain text.
How do I set up Dovecot to read users from a PostgreSQL database with bcrypt hashed passwords?
Dovecot fully supports the BLF-CRYPT password scheme since the recent 2.3 release apparently.
It shouldn't make a difference for PostgreSQL what kind of scheme is used, the password is just a text field in the database and it's stored and retrieved in its hashed textual form. The scheme used to hash is known by the first few characters of the password, for instance $2a$ for bcrypt.
Hashing the password can be can be done with doveadm -s BLF-CRYPT and the output copied into the password field of the database in the row corresponding to the user.
For the authentication, dovecot, like postfix, expects a user-supplied SQL query with some documented placeholders in its configuration (see password_query), so it doesn't need to assume any particular structure of a table or view of users.
I am very new to Powershell and was wondering if it is possible to accomplish the following, which is based on a requirement to change SQL passwords every 3 months and update all the websites whose web.config files have connections strings at the same time to the new SQL password.
Ideally the new SQL passwords, server names & databases could be stored in a file (SQL table, XML files, csv, etc) and the script reads in the file. Then the script changes the SQL Passwords based on the content of a table that contains the names of the servers and databases. Immediately after step 1, the script updates the web.configs connection strings in about 20 websites to the new password used in step 1. I guess I need a table to hold the path to the web.configs too. Then it repeats the process by changing a SQL password and updating another 20 websites.
Nice to have would be creating a backup copy of the web.config prior to modifying it and wrapping the script in transaction just in case the script encounters an error.
Thanks
Can i restore different dumps(databases) on a single database created through the database configuration assistant in oracle 10g.
i mean to say that the previous tablespaces must be overwritten by the new one thus saving the time to create new tablespace everytime we restore a dump file.
yes it is possile by creating a new user.the new user will act as a new schema and can exist with the previously imported data without overwriting it.
how ever if i want to import different data using the same user then the previously stored data must be dropped along with the user first,the agin the user must be created;
Command to do this is
DROP USER CASCADE;
This will drop the previously stored data without deleting the tablespaces thus saving time to create new tablespaces.
I am new to the Administration part of the Oracle server,Just want to know will deleting a user means data related to that user will also get deleted?
Thanks you.
Review cascade option for drop user command

Depends upon what you mean by "related". Every user in the database has a corresponding schema, with tables, indexes and so on. If you drop a user, their schema and all the data in it goes too. If the user has put data into other tables, that data does not go anywhere.
