In firebird4 we have improved hash() function in order to make it
support various kinds of hashes. But except hashes there are a lot of
other crypto-related tasks that may be useful to execute directly from
SP & triggers. Does it make sense to add functions (may be UDR?) for
signing something and verifying that sign or various cyphers to
encrypt/decrypt data? Please pay attention that database (specially
encrypted) is not bad place to store various keys in it.
