# hhhash

HTTP Headers Hashing

## Description

HTTP Headers Hashing (HHHash) is a technique used to create a

fingerprint of an HTTP server based on the headers it returns. HHHash

employs one-way hashing to generate a hash value for the set of header

keys returned by the server. See

 for more info.

## What’s Inside The Tin

The following functions are implemented:

- `build_hash_from_response`: Build a hash from headers in an curl

  response object

- `build_hash_from_url`: Build a hash from headers retrieved from a URL

- `hash_headers`: Build a hash from a vector of HTTP header keys

- `sha256`: Convience wrapper for digest::digest() with algo = “sha256”

  and serialize = FALSE

## Installation

``` r

remotes::install_github("hrbrmstr/hhhash")

```

NOTE: To use the ‘remotes’ install options you will need to have the

[{remotes} package](https://github.com/r-lib/remotes) installed.

## Usage

``` r

library(hhhash)

# current version

packageVersion("hhhash")

## [1] '0.1.1'

```

``` r

build_hash_from_url("https://www.circl.lu/")

## [1] "hhh:1:78f7ef0651bac1a5ea42ed9d22242ed8725f07815091032a34ab4e30d3c3cefc"

```

``` r

res <- curl::curl_fetch_memory("https://www.circl.lu/", curl::new_handle())

build_hash_from_response(res)

## [1] "hhh:1:78f7ef0651bac1a5ea42ed9d22242ed8725f07815091032a34ab4e30d3c3cefc"

```

``` r

c(

  "Date", "Server", "Strict-Transport-Security",

  "Last-Modified", "ETag", "Accept-Ranges",

  "Content-Length", "Content-Security-Policy",

  "X-Content-Type-Options", "X-Frame-Options",

  "X-XSS-Protection", "Content-Type"

) -> keys

hash_headers(keys)
