  1. # The secrets module is used for generating cryptographically strong random
  2. # numbers suitable for managing data such as passwords, account authentication,
  3. # security tokens, and related secrets.
  4. # In particularly, secrets should be used in preference to the default
  5. # pseudo-random number generator in the random module, which is designed for
  6. # modelling and simulation, not security or cryptography.
