Factory interface for creating AuthenticationProvider instances that use the Vert.x JDBC client. By default the hashing strategy is SHA-512. If you're already running in production this is backwards compatible, however for new deployments or security upgrades it is recommended to use the PBKDF2 strategy as it is the current OWASP recommendation for password storage. 
 NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen. /**

Provide a application configuration level on hash nonce's as a ordered list of
nonces where each position corresponds to a version.
The nonces are supposed not to be stored in the underlying jdbc storage but to
be provided as a application configuration. The idea is to add one extra variable
to the hash function in order to make breaking the passwords using rainbow tables
or precomputed hashes harder. Leaving the attacker only with the brute force
approach.
