Hi all,
This is Generic Access Control v1.0 beta. It uses the exportable secure
hash algorithm SHA-1 ported to Euphoria by Davi T. Figueiredo to limit
access to anything coded by an Euphoria program.
I'm trying to judge demand, so please e-mail me if you want this. If you=
find the beta useful, perhaps you can remember to vote for this program
when it goes on the website. (Robert, don't worry. SHA-1 is freely
exportable. No crypto here!)
The documentation hasn't been written yet. But here's a comprehensive
rough outline.
Just include ACCESS.E and you have access to the following seven routines=
:
loadAF() loads (or creates) an access database in the current directory
Quirk Note: The access database will be created in the current directory.=
=
For the beta release, I suggest you copy the two .E files into your
Euphoria program source directory and run the program from the source's
directory. I hope to make this unnecessary in the future. Also, you
cannot have two programs running ACCESS.E in the same directory, unless y=
ou
want the programs sharing the access database.
saveAF() save any additions/changes to the access database to disk
purgeAF() purges the entire access database on the disk
i =3D addAC(sequence username, sequence password)
Add the username and password to the access database in memory. The
password is hashed using SHA-1, which is a one way hash. i can be
AC_SUCCESS: successfully added
AC_FAIL: the username already exists
i =3D delAC(sequence username) deletes the username from the access datab=
ase
i can be
AC_SUCCESS deleted
NO_ENTRY no such username in access database
i =3D verify(sequence username, sequence password) finds the username in =
the
database, hashes the input password and compares it with the hash value i=
n
the database
i can be
GRANTED matches
DENIED passwords do not match
NO_ENTRY no such username in database
changepass(sequence username, sequence old_pass, sequence new_pass)
changes the password of the username. First verifies the old password an=
d
then replaces the hash of the old password to the hash of the new passwor=
d
i can be the same values as function verify
Please let me know about any comments or suggestions. Thanks.
Alan
