# rev-hash [](https://travis-ci.org/sindresorhus/rev-hash)
|
|
|
|
> Create a hash for file revving
|
|
|
|
It will create an `md5` hash from an input buffer or string, and truncate it to 10 characters, which is unique enough for this purpose.
|
|
|
|
If you think you need a different hash algorithm or a longer hash, [you're wrong](http://blog.risingstack.com/automatic-cache-busting-for-your-css/).
