Contact the person responsible for the data in your database.
Ask him which hashing algorithm should be used to verify the
license info provided by a user against the database info.

Note: there are many different hashing functions (e.g. "md5", "sha1",
"sha256", ...) and often their use involves an additionl secret
(besides the hashed data). Best get those details from a
knowledgable person than from us.
