• name: _sha
  • description: use module _sha
  • command-line: –withmod-_sha
  • command-line for negation: –withoutmod-_sha
  • option type: boolean option
  • default: False

Use the built-in _’sha’ module. This module is expected to be working and is included by default. There is also a pure Python version in lib_pypy which is used if the built-in is disabled, but it is several orders of magnitude slower.
