Factory interface for creating `io.vertx.ext.auth.AuthProvider` 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.

Attributes inherited from: `Object` `hash`, `string`

Methods
`computeHash` | `shared default String computeHash(String password, String salt)` Compute the hashed password given the unhashed password and the salt without nonce The implementation relays to the JDBCHashStrategy provided. Parameters: `password` the unhashed password `salt` the salt
`computeHash` | `shared default String computeHash(String password, String salt, Integer version)` Compute the hashed password given the unhashed password and the salt The implementation relays to the JDBCHashStrategy provided. Parameters: `password` the unhashed password `salt` the salt `version` the nonce version to use
`generateSalt` | `shared default String generateSalt()` Compute a salt string. The implementation relays to the JDBCHashStrategy provided.
`setAuthenticationQuery` | `shared default JDBCAuth setAuthenticationQuery(String authenticationQuery)` Set the authentication query to use. Use this if you want to override the default authentication query. Parameters: `authenticationQuery` the authentication query
`setNonces` | `shared default JDBCAuth setNonces(Array nonces)` 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. The implementation relays to the JDBCHashStrategy provided. Parameters: `nonces` a List of non null Strings.
`setPermissionsQuery` | `shared default JDBCAuth setPermissionsQuery(String permissionsQuery)` Set the permissions query to use. Use this if you want to override the default permissions query. Parameters: `permissionsQuery` the permissions query
`setRolePrefix` | `shared default JDBCAuth setRolePrefix(String rolePrefix)` Set the role prefix to distinguish from permissions when checking for isPermitted requests. Parameters: `rolePrefix` a Prefix e.g.: “role:”
`setRolesQuery` | `shared default JDBCAuth setRolesQuery(String rolesQuery)` Set the roles query to use. Use this if you want to override the default roles query. Parameters: `rolesQuery` the roles query
