labelHash

The labelhash function takes a ENS label as input and generates a hashed version of that label. The hashed label can be used for various purposes, such as storing the label in a database or comparing it with other labels.

The function takes a single parameter, name, which is the ENS label to be hashed. The function returns the hashed label as a string.

It's important to note that ENS labels can have certain forbidden characters and validation rules, so it's recommended to normalize ENS labels with UTS-46 normalization before passing them to labelhash. The built-in normalize function can be used for this.

The labelhash function is useful for a variety of use cases, such as:

• Storing ENS labels in a database: By hashing the labels, you can store them in a compact and efficient manner, while still being able to compare them with other labels.
• Comparing ENS labels: The hashed labels can be compared with other hashed labels to determine if they are the same or not.
• Generating ENS labels: The hashed labels can be used as a starting point for generating new ENS labels, by appending or prepending characters to the hashed label.

Overall, the labelhash function is a useful tool for working with ENS labels in a secure and efficient manner.
