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.

Doctrine Cache Encrypter
Having to encrypt your data at rest shouldn't keep you from using the open-source
tools you know and love. If you have data that needs a higher degree of security
than the rest of your cache, you can store and access it via an
EncryptingDecorator.
Caveats
Encryption and decryption are both expensive operations, and frequent reads from an encrypted data store can quickly become a bottleneck in otherwise performant applications. Use encrypted caches sparingly (i.e., do not use an encrypting decorator around your Doctrine Annotations cache).
Usage
This package provides two cache decorators, one that encrypts data using a pass phrase and one that does so with public and private keys. The implementation using a pass phrase is the more performant of the two but requires that you securely deploy a plaintext password.
First, create your Doctrine-based cache as you normally would:
Second, wrap your cache with an encrypting decorator:
Then use your $cache and $encryptedCache like you normally would:
Though your regular cache and encrypted cache share a storage layer and a
keyspace, they will not be able to read each other's data. The $encryptedCache
will return false if asked to read unencrypted data, and the regular $cache
will return gibberish if asked to read encrypted data.
Encrypting your cache without sharing secrets
If you'd rather not rely on a shared password, the EnvelopeEncryption\Decorator
can secure your sensitive cache entries using a public/private key pair.
The certificate can be a valid x509 certificate, a path to a PEM-encoded certificate file (the path must be prefaced with
file://), or a PEM-encoded certificate string. The private key can be a path to a PEM-encoded private key file (the path must be prefaced withfile://), or a PEM-encoded certificate string.
