ANN: M2Crypto 0.19

I am happy to announce the M2Crypto 0.19 release!

M2Crypto is the most complete Python wrapper for OpenSSL featuring RSA,
DSA, DH, HMACs, message digests, symmetric ciphers (including AES); SSL
functionality to implement clients and servers; HTTPS extensions to
Python's httplib, urllib, and xmlrpclib; unforgeable HMAC'ing
AuthCookies for web session management; FTP/TLS client and server;
S/MIME; ZServerSSL: A HTTPS server for Zope and ZSmime: An S/MIME
messenger for Zope. M2Crypto can also be used to provide SSL for Twisted.

Note: Python 2.6 shipped with optional timeout parameters to many
network modules; there is no support for these in M2Crypto 0.19.
Otherwise 2.6 is supported.

Changes:

- OpenSSL OBJ_* functions wrapped by Pavel Shramov
- OpenSSL ENGINE interface wrapped, providing support for smart cards,
by Martin Paljak and Pavel Shramov
- EVP.PKey.get_rs a() now returns RSA_pub, which fixes segmentation fault
when trying to encrypt using public key from X509 certificate,
by Ben Timby
- httpslib.ProxyH TTPSConnection now sends the required Host header,
by Karl Grindley
- Use the proxied User-Agent value in CONNECT requests, by James Antill
and Miloslav Trmac
- Fixed m2urllib.build_ opener when optional handlers were in use,
affected Python 2.5 and later, by Miloslav Trmac
- Reverted the incorrect GIL change done in 0.18 to
m2.passphrase_c allback, which caused a deadlock when called from
mod_python for example. Thanks to Michal Kochel and Keith Jackson.
- SSL.Connection. accept() passed wrong certificate to
postConnectionC heck callback
- httpslib.HTTPSC onnection now raises ValueError for illegal keyword
argument
- m2.pkey_write_p em[_no_cipher] changed to use the recommended (more
secure) PEM_write_bio_P KCS8PrivateKey (used by
PEM_write_bio_P rivateKey).
- X509.load_cert, load_cert_bio, load_cert_der_s tring,
new_stack_from_ der, load_request and load_crl now raise X509Error for
invalid data. Previously some of these raised a string as an error,
some did not raise but caused strange errors later, for example
x509.verify() would return -1.
- Fixed SSL.Connection. get_socket_read _timeout and
set_socket_read _timeout on 64bit platforms by adding
SSL.timeout.str uct_size() and using it instead of
hardcoded size for socket.getsocko pt
- X509_Store.load _info now returns the value from the underlying
m2.x509_store_l oad_locations call, and in case of error raises
X509Error
- Fixed SMIME.verify to raise the correct PKCS7_Error (used to raise
SMIME_Error) when verification fails with Python 2.6

Requirements:

* Python 2.3 or newer
o m2urllib2 requires Python 2.4 or newer
* OpenSSL 0.9.7 or newer
o Some optional new features will require OpenSSL 0.9.8 or newer
* SWIG 1.3.24 or newer required for building
o SWIG 1.3.30 or newer may be required with Python 2.5 or newer and
Python 2.4 with Py_ssize_t patches

Or use easy_install (may not work on all systems): easy_install M2Crypto

I tried to adapt the instructions for building the M2Crypto module (http://sandbox.rulemaker.net/ngps/m2/INSTALL.html) to build a version compatible with Python2.3, but I've had some mixed results.

Here's a wierd problem: I have a little test case for M2Crypto, which just opens up SSL connections to web servers and reads their certificates. This works fine. But if I execute socket.setdefaulttimeout(5.0) so that the sockets don't wait too long if there's no SSL server, I get

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
