1. createSystemRandom :: IO GenIO

   pcg-random	System.Random.PCG

   Seed a PRNG with data from the system's fast source of pseudo-random numbers. All the caveats of withSystemRandom apply here as well.

2. withSystemRandom :: (GenIO -> IO a) -> IO a

   pcg-random	System.Random.PCG

   Seed with system random number. (/dev/urandom on Unix-like systems and CryptAPI on Windows).

3. sysRandom :: IO Word64

   pcg-random	System.Random.PCG.Class

   Generate a random number using System.Entropy. Use RDRAND if available and XOR with /dev/urandom on Unix and CryptAPI on Windows. This entropy is considered cryptographically secure but not true entropy.

4. createSystemRandom :: IO GenIO

   pcg-random	System.Random.PCG.Fast

   Seed a PRNG with data from the system's fast source of pseudo-random numbers. All the caveats of withSystemRandom apply here as well.

5. withSystemRandom :: (GenIO -> IO a) -> IO a

   pcg-random	System.Random.PCG.Fast

   Seed with system random number. (/dev/urandom on Unix-like systems and CryptAPI on Windows).

6. createSystemRandom :: IO GenIO

   pcg-random	System.Random.PCG.Fast.Pure

   Seed a PRNG with data from the system's fast source of pseudo-random numbers. All the caveats of withSystemRandom apply here as well.

7. withSystemRandom :: (GenIO -> IO a) -> IO a

   pcg-random	System.Random.PCG.Fast.Pure

   Seed with system random number. ("/dev/urandom" on Unix-like systems, time otherwise).

8. createSystemRandom :: IO GenIO

   pcg-random	System.Random.PCG.Pure

   Seed with system random number. (/dev/urandom on Unix-like systems and CryptAPI on Windows).

9. withSystemRandom :: (GenIO -> IO a) -> IO a

   pcg-random	System.Random.PCG.Pure

   Seed with system random number. (/dev/urandom on Unix-like systems and CryptAPI on Windows).

10. createSystemRandom :: IO GenIO

    pcg-random	System.Random.PCG.Single

    Seed a PRNG with data from the system's fast source of pseudo-random numbers. All the caveats of withSystemRandom apply here as well.
