# JDBCHashStrategy 

###
Companion object JDBCHashStrategy

#### class JDBCHashStrategy extends AnyRef

Determines how the hashing is computed in the implementation

You can implement this to provide a different hashing strategy to the default.

20.  def setNonces(nonces: JsonArray): Unit

    Sets a ordered list of nonces where each position corresponds to a version.

    Sets 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.

    Nonces are dependent on the implementation. E.g.: for the SHA512 they are extra salt used during the hashing, for the PBKDF2 they map the number of iterations the algorithm should take * @param nonces a json array.
