- name: _md5
- description: use module _md5
- command-line: –withmod-_md5
- command-line for negation: –withoutmod-_md5
- option type: boolean option
- default: False

Use the built-in ‘_md5’ 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.
