To generate json user model with username, password_hash, email_id, created_at, updated_at, type mix phoenix.gen.json User users username:string email_id:string password_hash:string timestamps()

The following code sample demonstrates a quick and easy means of encrypting and decrypting files using the AES symmetric encryption algorithm. The code randomly generates the Salt and Initialization Vectors each time a file is encrypted, meaning that encrypting the same file with the same password ...

Acknowledgement This example is adapted from this article on type inference What is type Inference? Type Inference is the mechanism that allows the compiler to deduce what types are used and where. This mechanism is based on an algorithm often called “Hindley-Milner” or “HM”. See below some of th...
