Class JDBCHashStrategy


  • public class JDBCHashStrategy
    extends Object
    Determines how the hashing is computed in the implementation You can implement this to provide a different hashing strategy to the default.

    NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

        public JDBCHashStrategy​(Object delegate)
    • Method Detail

      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class Object
      • createSHA512

        @Deprecated
        public static JDBCHashStrategy createSHA512​(Vertx vertx)
        Deprecated.
        This is the current backwards compatible hashing implementation, new applications should prefer the PBKDF2 implementation, unless the tradeoff between security and CPU usage is an option.
        Parameters:
        vertx - the vert.x instance
        Returns:
        the implementation.
      • createPBKDF2

        @Deprecated
        public static JDBCHashStrategy createPBKDF2​(Vertx vertx)
        Deprecated.
        Implements a Hashing Strategy as per https://www.owasp.org/index.php/Password_Storage_Cheat_Sheet (2018-01-17). New deployments should use this strategy instead of the default one (which was the previous OWASP recommendation). The work factor can be updated by using the nonces json array.
        Parameters:
        vertx - the vert.x instance
        Returns:
        the implementation.
      • generateSalt

        @Deprecated
        public String generateSalt()
        Deprecated.
        Compute a random salt.
        Returns:
        a non null salt value
      • computeHash

        @Deprecated
        public String computeHash​(String password,
                                  String salt,
                                  int version)
        Deprecated.
        Compute the hashed password given the unhashed password and the salt
        Parameters:
        password - the unhashed password
        salt - the salt
        version - the nonce version to use
        Returns:
        the hashed password
      • getHashedStoredPwd

        @Deprecated
        public String getHashedStoredPwd​(JsonArray row)
        Deprecated.
        Retrieve the hashed password from the result of the authentication query
        Parameters:
        row - the row
        Returns:
        the hashed password
      • getSalt

        @Deprecated
        public String getSalt​(JsonArray row)
        Deprecated.
        Retrieve the salt from the result of the authentication query
        Parameters:
        row - the row
        Returns:
        the salt
      • setNonces

        @Deprecated
        public void setNonces​(JsonArray nonces)
        Deprecated.
        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
        Parameters:
        nonces - a json array.
      • isEqual

        @Deprecated
        public static boolean isEqual​(String hasha,
                                      String hashb)
        Deprecated.
        Time constant string comparision to avoid timming attacks.
        Parameters:
        hasha - hash a to compare
        hashb - hash b to compare
        Returns:
        true if equal
