Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Calendar Versioning.

The first number of the version is the year. The second number is incremented with each release, starting at 1 for each year. The third number is for emergencies when we need to start branches for older releases.

You can find our backwards-compatibility policy here.

Unreleased

23.1.0 - 2023-06-21

Removed

  • Support for Python 2.7, 3.5, and 3.6 has been dropped.

Added

  • Support for RFC 4880 OpenPGP private & public keys: pem.OpenPGPPublicKey and pem.OpenPGPPrivateKey. #72
  • Support for intra-payload headers like the ones used in OpenPGP keys using the meta_headers property. #75
  • pem.parse_file() now accepts also pathlib.Path objects.
  • pem.parse() now also accepts str.
  • Added text_payload, bytes_payload and decoded_payload properties to all PEM objects that allow to directly access the payload without the envelope and possible headers. #74

21.2.0 - 2021-04-07

Added

  • Added support for pem.OpenSSLTrustedCertificate (-----BEGIN TRUSTED CERTIFICATE-----), as defined in openssl x509 manual. #28

21.1.0 - 2021-01-22

Added

  • Added support for DSA private keys (BEGIN DSA PRIVATE). This is also the OpenSSH legacy PEM format. #49
  • Added support for pem.SSHPublicKey (---- BEGIN SSH2 PUBLIC KEY ----), as defined in RFC 4716. #46
  • Added support for pem.SSHCOMPrivateKey (---- BEGIN SSH2 ENCRYPTED PRIVATE KEY ----), the SSH.com / Tectia private key format (plain or encrypted). #46

20.1.0 - 2020-01-06

Changed

  • Carriage returns (\r) are now stripped before hashing pem objects to provide consistent hashes across platforms. #40

19.3.0 - 2019-10-16

Removed

  • Python 3.4 is not supported anymore. It has been unsupported by the Python core team for a while now and its PyPI downloads are negligible.

    It's very unlikely that pem will break under 3.4 anytime soon, but we don't test it anymore.

Added

  • Added support for pem.OpenSSHPrivateKey (OPENSSH PRIVATE KEY). OpenSSH added a new BEGIN label when it switched to a proprietary key encoding. #39

19.2.0 - 2019-08-06

Added

  • Added support for pem.ECPrivateKey (EC PRIVATE KEY).

19.1.0 - 2019-03-19

Added

  • You can now load encrypted PKCS#8 PEM key as pem.Key.
  • Added support for pem.PublicKey (PUBLIC KEY).
  • Added support for pem.RSAPublicKey (RSA PUBLIC KEY).

18.2.0 - 2018-10-09

Added

  • Added pem.CertificateRevocationList for certificate revocation lists (CRLs). #32

18.1.0 - 2018-06-23

Removed

  • pem.certificateOptionsFromFiles() and pem.certificateOptionsFromPEMs() have been removed after three years of deprecation. Please use pem.twisted.certificateOptionsFromFiles() pem.twisted.certificateOptionsFromPEMs() instead.
  • Diffie-Hellman support for Twisted older than 14.0 has been removed.

Added

  • pem now ships with typing information that can be used by type checkers like Mypy.
  • PEM objects now have an obj.sha1_hexdigest property with the SHA-1 digest of the stored bytes as a native string. This is the same digest as the one that is used by the PEM objects' __repr__s.
  • PEM objects now have an obj.as_text() method that returns the PEM-encoded content as unicode, always.

17.1.0 - 2017-08-10

Added

16.1.0 - 2016-04-08

Deprecated

  • Passing dhParameters to pem.twisted.certifateOptionsFromPEMs and certificateOptionsFromFiles is now deprecated; instead, include the DH parameters in the PEM objects or files.

Removed

  • Python 3.3 and 2.6 aren't supported anymore. They may work by chance but any effort to keep them working has ceased.

    The last Python 2.6 release was on October 29, 2013 and isn't supported by the CPython core team anymore. Major Python packages like Django and Twisted dropped Python 2.6 a while ago already.

    Python 3.3 never had a significant user base and wasn't part of any distribution's LTS release.

Added

  • pem.twisted.certificateOptionsFromPEMs and certificateOptionsFromFiles will now load Ephemeral Diffie-Hellman parameters if found. #21
  • PEM objects now have an as_bytes method that returns the PEM-encoded content as bytes, always. #24

Fixed

  • PEM objects now correctly handle being constructed with unicode and bytes on both Python 2 and 3. #24
  • PEM objects are now hashable and comparable for equality. #25

16.0.0 - 2016-02-05

Added

  • PKCS #8 keys are now supported. #14
  • pem is now fully functional without installing Twisted. #16

15.0.0 - 2015-07-10

Deprecated

  • The usage of Twisted helpers from the pem module is deprecated. Use their pendants from the pem.twisted module now.
  • The usage of the backport of ephemeral Diffie-Hellman support is hereby deprecated. Nobody should use a Twisted release that is older than 14.0.0 because it contains essential SSL/TLS fixes.

Changed

  • Support PEM strings that do not end with a new line. #12
  • Support PEM strings that end with \r\n.
  • The Twisted-related helpers have been moved to pem.twisted.

0.3.0 - 2014-04-15

Changed

  • Load PEM files as UTF-8 to allow for non-ASCII comments (like in certifi).
  • Allow keys, primary certificates, and chain certificates to occur in any order.

0.2.0 - 2014-03-13

Added

  • Add forward-compatible support for DHE.

0.1.0 - 2013-07-18

Initial release.
