rp1 is a parallel port device, generating 5-bit hardware random numbers based on hazards.
This generator is hot swappable and has low power consumption (approx. 0.1 W). The device is powered from the parallel port - no batteries or cables required.
- Speed: 2 MByte/s (the Parallel Port can only read approx. 1 MByte/s)
- Dimensions: 6 x 5 x 1.5 cm
- Weight: 55 g
rw1 is an ISA card, generating 16-bit hardware random numbers based on hazards.
- Speed (without overclocking): 16.67 MByte/s (the ISA Bus can only read approx. 2 MByte/s)
- Dimensions (incl. IBM Bracket): 18 x 12 x 2 cm
- Weight: 200 g
This card is hot swappable and the random bit files produced with the corresponding device driver do not contain any significant correlations and also pass the 15 diehard tests.
