Class ArgonSettings

java.lang.Object
com.codingchili.core.security.ArgonSettings
public class ArgonSettings extends Object
Contains default argon2 parameters for password hashing. These can be configured in the Configurations.security().

Please note that these settings will only be used when creating new hashes, for verifying old hashes the parameters encoded in the hash will be used instead.

These defaults are tuned to hash/verify in approximately 10ms on a recent desktop CPU. The parameters must be tuned to incur the most affordable time penalty for maximum security.

  • Method Details

    • getIterations

      public int getIterations()
      Returns:
      the number of iterations to perform when hashing.

    • setIterations

      public void setIterations​(int iterations)
      Parameters:
      iterations - the number of iterations to perform when hashing. More iterations requires more processing power to verify.

    • getMemory

      public int getMemory()
      Returns:
      the memory requirements for hashing in kibibytes.

    • setMemory

      public void setMemory​(int memory)
      Parameters:
      memory - the memory requirements for hashing in kibibytes, more memory means that ASICs will perform worse. At least while memory is expensive.

    • getParallelism

      public int getParallelism()
      Returns:
      the number of threads to use for computation.

    • setParallelism

      public void setParallelism​(int parallelism)
      Parameters:
      parallelism - the number of threads for computation.

    • getHashLength

      public int getHashLength()
      Returns:
      the total length of the generated hash in bytes.

    • setHashLength

      public void setHashLength​(int hashLength)
      Parameters:
      hashLength - set the length of the hash in bytes.

    • getSaltLength

      public int getSaltLength()
      Returns:
      the length of the generated salt in bytes.

    • setSaltLength

      public void setSaltLength​(int saltLength)
      Parameters:
      saltLength - the length of the generated salt in bytes.
