Let’s begin with thinking of which all places do we in fact require to place file encryption into action and how do we execute them Other than the feasible encryption done at the Database end, there are two popular techniques of applying encryption – One, which is done at the client side the one we will mainly speak about in this short article and Two, which is done at the web server side i.e., the demand lugs the actual password and also at the web server it is secured to be processed further.
The former of both is certainly much safer to have as it removes the risk of the demand being intercepted between before it in fact reaches the web/app web server. Well you can claim that the information packaged in a HTTP post demand is automatically encrypted in instance of HTTPS, but an additional degree of file encryption will include in the safety of the internet application. Of course, the execution must not be too much time consuming otherwise the benefits of having an extra safe and secure application will be ruled over by the frustration it could cause to its end-users. Though, it depends upon the actual execution, however possibly the recommended selection in highly safe and secure systems is that the real password must not be revealed anywhere in system, which indicates the encrypted password saved in DB is brought and most likely not decrypted back to actual password which the end-user makes use of private messenger, however instead a few other kind which is matched with the decrypted one at the middle-tier to confirm the customer.
The gone into password is very first secured at the client side using the Public Key ‘public key1’ in the above diagram and then the encrypted password gets to the App Server where it is decrypted an equivalent Private Key ‘private key1’ in the above representation. App Server likewise fetches the password saved in the data source, which may require to be decrypted utilizing one more Private Key ‘personal key2’ in the above representation. Now, the execution of the formulas and the generation of the keys must be such that both the decrypted passwords ‘decryptedpwd1’ and also ‘decryptedpwd2’ need to match equivalent for all the legitimate situations and also they need to be unequal otherwise.
