#GET PLAIN TEXT FROM ENCRYPTED TEXT HOW TO#

Then we hash a user-entered password and compare that to the hash in the database.

Encryption is reversible (provided you have the decryption key)įor regular authentication, we use store password-hashes in the database.A one-way hash is non-reversible (hence the term one-way).

#GET PLAIN TEXT FROM ENCRYPTED TEXT HOW TO#

To store and to view is one thing, other thing is how to secure such application from various kinds of encrypted posts hijacks, database dumps and similar attacks? Technology itself probably is not the most important thing here but i'm going to make this application using php and laravel framework. I will just add to it that let's assume single password or set of passwords is a blog post to view in a plain text only by author of such post and under specific circumstances by admin and moderator. Is what i want even possible to achieve? Or is there any other approach i should take instead of hashing but still secure to store multiple passwords to multiple services by a single user? Standard way to store passwords for authentication is to hash them for example with bcrypt or other method with salt added to it and such encryption doesn't let you to decrypt passwords easily. This means passwords would need to be stored encrypted but being possible to display to a user in plain text. In such case we have few things to consider: basic security measures by encrypting stored passwords with hash, how to protect passwords in case if they would have been stolen from database by, for example, dumping the database by attacker.

Let's say i want to create a service where user can store and VIEW in plain text its passwords for multiple services. I have a security related dilemma which i'm unable to figure out by myself from my knowledge about web applications security. So let me just copy and paste what i asked there: I've already asked that question at stackoverflow but i was informed it is a bit too broad and relies more in here instead.
