PEP 247 specifies a standard Python API for cryptographic hashing algorithms such as MD5 or SHA, to make it easier to switch between different implementations. After a round of comments from the gang on the python-crypto list, I believe the PEP is complete, and am requesting one last round of comments on it. The HTML version is at: http://python.sourceforge.net/peps/pep-0247.html If no one points out any problems with the text, then the PEP can be considered finished, and we can begin checking that hash modules comply with the API. --amk
