cypher format

We use the .cyp file extension for the encrypted file. A .cyp is nothing else than a zip file containing the following shit.

1. a data.encrypted containing the encrypted data
2. a meta_data.yml file containing the meta data of the encrypted file
   • symetric encryption algorithm
   • mode
   • encrypted symetric key
   • hash of the encrypted data (always use full for validation)
3. a 'signature' file with the signature of the meta_data.yml file
