# encfs-afero
Used encryption algorithm AES-CTR.
File format:
* content.txt - Original file(Encrypted with AES/CTR)
* content.txt.__encfile - Meta file(original file name and IV)
How AES/CTR works explain:
_Image is from: https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation_
Sample code:
```go
package main
import "github.com/jht5945/encfs-afero/encfs"
func main() {
fs := encfs.NewEncFs(encfs.NewEncryptionMasterKey(make([]byte, 32)))
f, err := fs.Create("aa")
if err != nil {
println("Error: ", err)
return
}
f.WriteString("hello world")
}
```
Sample code will generate fiels:
```shell
-rw-r--r-- 1 hatterjiang staff 11 Dec 21 10:56 aa
-rw-r--r-- 1 hatterjiang staff 45 Dec 21 10:56 aa.__encfile
```
`aa` is encrypted file, and `aa.__encfile` is meta file.
```shell
$ cat aa.__encfile | jq .
{
"name": "aa",
"iv": "ue0IcDegDuwZjNgND1vUIQ=="
}
```
File name can be encrypted after set `FileNameIv` in `EncryptionMasterKey`.
