6.2 (2026-10-21)

• Move package metadata from setup.py to pyproject.toml.

• Add support for Python 3.14, 3.15.

• Drop support for Python 3.10, 3.9.

6.1 (2025-09-12)

• Replace pkg_resources namespace with PEP 420 native namespace.

• Replace deprecated pkg_resources with importlib.metadata.

6.0 (2025-01-14)

• Drop support for crypt password manager. Its base library is long deprecated and was removed in Python 3.13.

5.0 (2025-01-14)

• Add support for Python 3.11. 3.12, 3.13.

• Drop support for Python 2.7, 3.5, 3.6, 3.7, 3.8.

4.4 (2022-09-01)

• Add support for Python 3.7, 3.8, 3.9, 3.10.

• Drop support for Python 3.4.

4.3.1 (2017-09-01)

• Fix running configure.zcml when zope.security is installed. See issue 15.

4.3.0 (2017-08-31)

• Added a bcrypt-based password manager (available only if the bcrypt library is importable). This manager can also check passwords that were encoded with z3c.bcrypt. If that package is not installed, then configure.zcml will install this manager as a utility with both the BCRYPT (preferred) and bcrypt names for compatibility with it. (See https://github.com/zopefoundation/zope.password/issues/10)

• Add a bcrypt_kdf password manager. This allows tunable numbers of rounds. See https://github.com/zopefoundation/zope.password/issues/9

• Fix the zpasswd console script on Python 3.

• Update the zpasswd script to use argparse instead of optparse.

• Use hmac.compare_digest when checking passwords to prevent timing analysis. This requires Python 2.7.7 or above.

• Add support for Python 3.6.

• Drop support for Python 3.3 and Python 2.7.6 and below.

• Drop support for python setup.py test.

4.2.0 (2016-07-07)

• Drop support for Python 2.6.

• Converted documentation to Sphinx, including testing doctest snippets under tox.

• Add support for Python 3.5.

4.1.0 (2014-12-27)

• Add support for PyPy. (PyPy3 is pending release of a fix for: https://bitbucket.org/pypy/pypy/issue/1946)

• Add supprt for Python 3.4.

• Add support for testing on Travis.

4.0.2 (2013-03-11)

• Fix some final resource warnings.

4.0.1 (2013-03-10)

• Fix test failures under Python 3.3 when warnings are enabled.

4.0.0 (2013-02-21)

• Make zpasswd a proper console script entry point.

• Add tox.ini and MANIFEST.in.

• Add support for Python 3.3

• Replace deprecated zope.interface.implements usage with equivalent zope.interface.implementer decorator.

• Drop support for Python 2.4 and 2.5.

• Add a new IMatchingPasswordManager interface with a ‘match’ method, which returns True if a given password hash was encdoded with the scheme implemented by the specific manager. All managers in this package implement this interface.

• Use “{SHA}” as the prefix for SHA1-encoded passwords to be compatible with RFC 2307, but support matching against “{SHA1}” for backwards compatibility.

• Add a crypt password manager to fully support all methods named in RFC 2307. It is contained in the legacy module however, to flag crypt’s status.

• Add a SMD5 (salted MD5) password manager to fully support all encoding schemes implemented by OpenLDAP.

• Add a MySQL PASSWORD() (versions before 4.1) password manager, as also found in Zope2’s AccessControl.AuthEncoding module.

• Remove the useless, cosmetic salt from the MD5 and SHA1 password managers, and use base64 encoding instead of hexdigests. This makes the output of these managers compatible with other MD5 and SHA1 hash implementations such as RFC 2307 but doesn’t lower it’s security in any way. Checking passwords against old, still ‘salted’ password hashes with hexdigests is still supported.

• Use the standard_base64encode method instead of url_base64encode to maintain compatibility with LDAP.

3.6.1 (2010-05-27)

• The SSHAPasswordManager.checkPassword() would not handle unicode input (even if the string would only contain ascii characters). Now, the encoded_password input will be encoded to ascii, which is deemed safe as it should not contain non-ascii characters anyway.

3.6.0 (2010-05-07)

• Remove zope.testing dependency for tests.

• Update some copyright headers to comply to repository policy.

• Add zpasswd script formerly hold in zope.app.server. Contrary to former zpasswd script, which used “Plain Text” as default password manager, now SSHA is used as default.

3.5.1 (2009-03-14)

• Make security protection directives in configure.zcml execute only if zope.security is installed. This will allow reuse of the configure.zcml file in environments without zope.security, for example with repoze.zcml.

• Add “Password Manager Names” vocabulary for use with zope.schema and zope.component, like it was in zope.app.authentication. It’s an optional feature so it doesn’t add hard dependency. We use “vocabulary” extra to list dependencies needed for vocabulary functionality.

3.5.0 (2009-03-06)

First release. This package was splitted off from zope.app.authentication to separate password manager functionality that is greatly re-usable without any bit of zope.app.authentication and to reduce its dependencies.
