# Encrypted Request + Response Payloads Middleware
|
|
|
|
Shows an example of a `from_fn` middleware that:
|
|
|
|
1. extracts a JSON request payload;
|
|
1. decrypts a data field;
|
|
1. re-encodes as JSON and re-packs the request;
|
|
1. calls the wrapped service;
|
|
1. unpacks the response and parses a similarly structured JSON object;
|
|
1. encrypts the data field;
|
|
1. re-packs the response.
|
|
|
|
All this to say, it provides a (fairly brittle) way to have handlers not need to care about the encryption and decryption steps.
|
|
|
|
## Usage
|
|
|
|
Using [HTTPie] throughout for simplicity.
|
|
|
|
```console
|
|
$ http POST :8080/encrypt id:=1234 data=abcde > tmp.json
|
|
HTTP/1.1 200 OK
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"id": 1234,
|
|
"data": "kq6MKdP+I0hoI7YC7CN39yamx67T",
|
|
"nonce": "dW5pcXVlIG5vbmNl"
|
|
}
|
|
|
|
$ cat tmp.json | http -v POST :8080/reverse
|
|
HTTP/1.1 200 OK
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"data": "UL4PeOr9Di8xpFEJZgylJ5K8R7vW",
|
|
"nonce": "dW5pcXVlIG5vbmNl"
|
|
}
|
|
```
|
|
|
|
The server logs would look something like
|
|
|
|
```plain
|
|
[INFO middleware_encrypted_payloads] creating encrypted sample request for ID = 1234
|
|
[INFO actix_web::middleware::logger] 127.0.0.1 "POST /encrypt HTTP/1.1" 200 76 "-" "-" 0.000393
|
|
...
|
|
[INFO middleware_encrypted_payloads] decrypting request 1234
|
|
[INFO middleware_encrypted_payloads] request 1234 with data: abcde
|
|
[INFO middleware_encrypted_payloads] response 1234 with new data: edcba
|
|
[INFO middleware_encrypted_payloads] encrypting response 1234
|
|
[INFO actix_web::middleware::logger] 127.0.0.1 "POST /reverse HTTP/1.1" 200 66 "-" "-" 0.000425
|
|
```
