   1 # hashgood
   2 A CLI tool for easily verifying a downloaded file's checksum.

   4 Wouldn't it be nice if your computer compared the hash for you?

   9 Read the MD5, SHA1 or SHA256 hash from:
  10
  11 * Command line argument
  12 * SHASUMS-style check files (`-c`)
  13 * Raw hash in a file/STDIN (`-c`)
  14 * The clipboard (`-p`)
  15
  16 ...or just run `hashgood` against the input and receive all three at once.
  17
  18 This program arose from dissatisfaction with the [workarounds required for traditional tools](https://thomask.sdf.org/blog/2019/05/05/techniques-for-verifying-shasums-conveniently.html).

  20 ## Installing
  21
  22 If you have a working Rust toolchain you can install `hashgood` from crates.io:
  23
  24 ```
  25 cargo install hashgood --features paste
  26 ```
  27
  28 Pre-compiled binaries for common platforms can be downloaded [from the releases page](https://github.com/thombles/hashgood/releases). Otherwise you can build it yourself; see the next section.
  29
  30 ## Compiling
  31
  32 `hashgood` targets stable Rust. With a Rust toolchain installed, clone the repository and run:
  33
  34 ```
  35 cargo build --release
  36 ```
  37
  38 Take the compiled executable from `target/release/hashgood`.
  39
  40 To include support for pasting from the clipboard with `-p`, specify the extra feature. Note that on Linux this requires several extra libraries: `libxcb1-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-render0-dev`
  41
  42 ```
  43 cargo build --release --features paste
  44 ```

  46 ## Goals
  47
  48 * Be forgiving and deliver what the user wants with a minimum of fuss. They just want to check this hash, damnit.
  49 * Don't let users be tricked - be explicit about checksum types and the sources of those checksums that are being compared.
  50 * As much cross-platform support as is practical.
  51
  52 ## Non-goals
  53
  54 * Scriptability. This is an interactive tool.
  55 * Support for any unusual scenarios that could compromise smooth operation. (e.g., text mode, uncommon hash types)
  56
  57 ## Future ideas
  58
  59 * Nominate a default (downloads) directory and auto-select the most recently created file in that directory as input.
