FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package lara-file-encrypter
LaraFileEncrypter: Secure your files in Laravel with AES-256 encryption, without persistent key storage hassle.
LaraFileEncrypter is a Laravel package, designed to enhance file security in your applications. With a straightforward integration, it enables you to easily implement AES-256 encryption. What sets LaraFileEncrypter apart is its unique approach: delivering maximum security without the need for key storage. Now, securing your files becomes a straightforward process, ensuring data confidentiality without added complexity.
How does it work?
LaraFileEncrypter simplifies file security by eliminating the need to manage encryption keys. Instead, the process relies on the use of a user-chosen password.
When encrypting a file, LaraFileEncrypter generates an encryption key based on the provided password. It's this key, derived from the password, that is used to secure your files using the AES-256 algorithm.
This approach removes the necessity of storing or managing separate encryption keys. By choosing a robust password, you ensure effective protection of your files without the complexity associated with traditional key management.
Pros and cons
| Pros | Cons |
|---|---|
| No key storage | Loss of password leads to unrecoverable file |
| Each user can encrypt their files with a unique password | AES keys potentially less robust than truly random methods |
| No modifications needed on the files infrastructure or database side | Potentially predictable keys |
