A bundle for file encryption under symfony

QFileEncryptionBundle

The QFileEncryption Bundle is a symfony bundle that attempts to ease files encryption, _(*1)

• GnuPG is used to encrypt/decrypt files
• Automatically rename and associate encrypted files
• Can be used to generate a download link and immediately delete the decrypted file

The main goal is to provide a simple PHP interface between the well known GnuPG and your application. For a brief description on how the bundle handle the procedures: * It can generate a key pair for a given user (with a passphrase of course) and store them in the specified gnupg home (in the config.yml). The point is that it will not store the keypair in the main GPG database but will create a local trust database for each user and will not perturb the main functionning of the host with these keys. * For the encryption part, the bundle take the actual path of the file we want to encrypt, store the original name and generate a new one for this file, encrypt and remove the original file. The association is then stored in database * For the decryption part, the bundle takes a stored encrypted file (QFile), a user associated key (QKey) and a passphrase (which is checked before trying decryption). It then try to decrypt the file, store it the /tmp directory generate a BinaryFileResponse (a response you can use to generate a download link in your application) and then remove the temporary decrypted file., _(*2)
