How to encrypt and decrypt Table data in postgres

For encrypting and decrypting , we must use the bytea data type on the column which we implement. Bcoz bytea will use the pgcrypto method by default.

However, you will need to create the pgcrypto extension to enable these functions as they are not pre-defined in PostgreSQL/PPAS.

Example

CREATE EXTENSION pgcrypto;

CREATE TABLE userinfo (username varchar(20), password bytea);

>>    Inserting the data in an encrypted format

INSERT INTO userinfo VALUES(' suman ',encrypt('111222','password','aes'));

select * from userinfo ;








>>    Retrieving the data as decrypted format

SELECT decrypt(password,decode('password','escape'::text),'aes'::text) FROM userinfo;

Configure Impersonation Authentication in IIS8 for MVC Application

Impersonation is when ASP.NET executes code in the context of an authenticated and authorized client. By default, ASP.NET does not use impersonation and instead executes all code using the same user account as the ASP.NET process, which is typically the ASPNET account. There are 5 below steps by which we can establish Impersonation configuration in our secured application environment. 1.)    Creation of Application/Proxy user where Application is hosted. 2.)    Give appropriate access to the user. 3.)    Create Database Login user on database. 4.)    Authenticate User and provide credential on IIS. 5.)    Then Configure web.config on Application.
