What Is AHash Algorithm


Namespace: VFP
See also Hash Algorithms
A hash algorithm converts a string of arbitrary length into a single number that's most likely different for different input strings.
Hash algorithms are very useful in security matters.

For example, take a look at the following code:
lnCode=Hash(password)
select passwords
if lnCode=passwords.code
    ***password is ok
else
    *** invalid password
endif

In this way you don t have to store the password in a table.
