One of the most common questions around authentication schemes in the APEX community is how to use a simple table of usernames and passwords for authentication In general, I strongly advise developers to leverage an identity management solution such as Oracle Access Manager, because it provides many benefits, not the least of which is the ability to authenticate many systems, not just an APEX application However, this question is asked so often that it is beneficial to provide an example here It is also a great opportunity to demonstrate the use of the DBMS_CRYPTO package in the context of APEX One of the key concepts to take away from this example is this: Never store passwords in clear text Many people use the same password or subset of passwords for all applications This means it is very likely that at least some of the username/password sets stored in your table could also be used to access a person s online applications, including financial institutions This scenario was the subject of several high-visibility data breaches and represents a very real security risk The question is, How do you securely store a password in a database table The answer: You don t store it at all; you store a cryptographic hash of the password instead This is exactly how the Oracle Database and APEX authenticate users Here s how this solution works: 1 A password is run through a one-way hash algorithm and the resulting value is stored in the table For example, let s say the user s password is welcome and the hash of welcome is #H*8F@90 2 When a user attempts to log into the application, she enters the password of elcome 3 This password is run through the same one-way hash algorithm The resulting hash is Z;&R3! 4 We then compare the two hash values Since they are not equal, authentication fails 5 The user now enters the correct password of welcome 6 The resulting hash of welcome is #H*8F@90, which is then compared to the hash stored in the table 7 Since #H*8F@90 = #H*8F@90, the user is now authenticated In this example, the term hash was used for brevity The reality is that the hash algorithms included with most software distributions, including the DBMS_CRYPTO package, are well known As such, an attacker could generate a table of common passwords and their corresponding hash values If the attacker gains access to a table, he would probably be able to determine one or more passwords by matching the stored hash with his table of hash values To combat this threat, our example will use a message authentication code (MAC) algorithm These algorithms also take in a key to generate the hash, so an attacker must know both the algorithm and the key to get access Using a sufficiently long and random key will all but eliminate this threat You should store this key in a secure location that is not on the server running the database If this key is compromised, it will be significantly easier for an attacker to generate a hash table and compromise passwords.

For this example, we ll use DBMS_CRYPTORANDOMBYTES to generate a 16 byte key:

Now we ll use following table to store usernames and passwords The user SEC_ADMIN will own this table and related packages

The following package will be used to create and authenticate users Note the use of EXECUTE IMMEDIATE for any queries or DML against the APPLICATION_USERS table In the event that someone does gain access to our table, he cannot simply query one of the dictionary views such as DBA_DEPENDENCIES to determine the package used to set the password This is certainly not a foolproof technique, but does make it more challenging to dissect the logic associated with password hashes
