  • Method Details

    • imohash1_0_2

      static FileHasher128 imohash1_0_2()
      Returns a FileHasher128 implementing version 1.0.2 of the Imohash algorithm using default parameters.

      This implementation is compatible with the Go reference implementation imohash.go.

      For a description of the algorithm see here.

      This algorithm does not return a uniformly distributed hash value.

      Returns:
      a file hasher instance

    • imohash1_0_2

      Returns a FileHasher128 implementing version 1.0.2 of the Imohash algorithm using default parameters.

      This implementation is compatible with the Go reference implementation imohash.go.

      For a description of the algorithm and the parameters see here.

      This algorithm does not return a uniformly distributed hash value.

      Parameters:
      sampleSize - the sample size
      sampleThreshold - the sample threshold
      Returns:
      a file hasher instance
