Create credentials database — create_db • shinymanager

Create a SQLite database with credentials data protected by a password.

create_db(
  credentials_data,
  sqlite_path,
  passphrase = NULL,
  flags = RSQLite::SQLITE_RWC
)

credentials_data

A data.frame with information about users, user and password are required.

sqlite_path

Path to the SQLite database.

passphrase

A password to protect the data inside the database.

flags

RSQLite::SQLITE_RWC: open the database in read/write mode and create the database file if it does not already exist; RSQLite::SQLITE_RW: open the database in read/write mode. Raise an error if the file does not already exist; RSQLite::SQLITE_RO: open the database in read only mode. Raise an error if the file does not already exist

The credentials data.frame can have the following columns:

• user (mandatory) : the user's name.

• password (mandatory) : the user's password.

• admin (optional) : logical, is user have admin right ? If so, user can access the admin mode (only available using a SQLite database). Initialize to FALSE if missing.

• start (optional) : the date from which the user will have access to the application. Initialize to NA if missing.

• expire (optional) : the date from which the user will no longer have access to the application. Initialize to NA if missing.

• applications (optional) : the name of the applications to which the user is authorized, separated by a semicolon. The name of the application corresponds to the name of the directory, or can be declared using : options("shinymanager.application" = "my-app")

• additional columns : add others columns to retrieve the values server-side after authentication
