### 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
|
|
func (this *RsaSha512) encrypt() ([]byte, error) {}
