Cryptographically secure pseudorandom number generator in Sass. Well that is easy to do with this custom `crypto()` handler!
Start by registering a Sass function with the name `crypto()`. Now when `crypto()` is found in Sass, the cryptotext Go function will be called.
Input
``` sass
div { text: crypto(); }
```
Output
``` css
div {
text: 'c91db27d5e580ef4292e'; }
```
Sass function written in Go
``` go
func cryptotext(ctx context.Context, usv libsass.SassValue) (*libsass.SassValue, error) {
c := 10
b := make([]byte, c)
_, err := rand.Read(b)
if err != nil {
return nil, err
}
res, err := libsass.Marshal(fmt.Sprintf("'%x'", b))
return &res, err
}
```
