# Sub-Resource Integrity Generator Scripts
|
|
|
|
Basic scripts to generate SRI hashes for a given file. POSIX-compliant shell script for use on *nix and PowerShell for use on Windows.
|
|
|
|
## linux script
|
|
|
|
- This script *requires* openssl be installed and will exit if it cannot find openssl.
|
|
- You can rename *sri* to anything you like.
|
|
- I suggest copying *sri* somewhere like */usr/local/bin* or */usr/bin* so it can be run easier and from anywhere
|
|
- Complete help is included in the script. Simply run without any parameters or run with '*--help*'
|
|
|
|
### examples
|
|
|
|
Assuming you have *not* copied the script to your path and it is located in your home directory:
|
|
|
|
```bash
|
|
cd ~
|
|
./sri -f /var/www/css/style.css
|
|
```
|
|
|
|
If copied to a directory in your path like */usr/local/bin*, then you can simplify things by running it directly from where the file you want to hash is located:
|
|
|
|
```bash
|
|
cd /var/www/css
|
|
sri -f style.css
|
|
```
|
|
|
|
### troubleshooting
|
|
|
|
About the only thing that can go wrong is the script not being marked executable. In that case, simply make it executable:
|
|
|
|
```bash
|
|
# make executable
|
|
chmod +x /path/to/sri
|
|
# verify
|
|
ls -lA /path/to/sri
|
|
# output something like:
|
|
# -rwxr-xr-x 1 user user 3622 Jun 20 01:18 sri
|
|
# note the x's --> -rwXr-Xr-X (capitals for emphasis)
|
|
```
