User Hash


Returns a secure one-way hash of a string in a way that only the user can calculate. Use this so that a user can "sign" a string and later check that it has not been modified.

It is astronomically improbable that two strings have the same hash, or that a string can be derived from a hash by brute force.

The hash is sensitive to changes in the user setup, such as password change, so this should only be used for hashing strings as part of a short-term process.

Use the Hash service if you want to hash a string in a way that another user will create the same hash.




<hash>hashed string</hash>
