XSLT and gettext?

[KW]

I'm looking for a nice way to do i18n with XSLT, preferably using the
gettext framework. Currently I'm using 4Suite for XSLT processing. Do
you know of any solutions to this problem?

If no solutions currently exist, I'll try to write something myself. Any
ideas on how to do this properly? Any existing python code to start with?

I was thinking about wrappingg the text in a new XML tag, say  and
processing this to generate an XSL for alle languages, but it will also
require printf like substitution to do this properly.

Kind regards,

PHP's openssl_sign() using M2Crypto?

[KW]

I'm trying to convert some PHP code using OpenSSL to Python and I'm stuck 
on openssl_sign() which uses an RSA private key to compute a signature.

Example PHP code:
  $privkeyid = openssl_get_privatekey($priv_key, $key_pass);
  openssl_sign($data, $signature, $privkeyid);
  openssl_free_key($privkeyid);

I've tried several permutations of the stuff in M2Crypto.EVP but I can't get
it to work...

The openssl module in PHP basicly does this (C code): 
  EVP_SignInit(&md_ctx, EVP_sha1());
  EVP_SignUpdate(&md_ctx, data, data_len);
  EVP_SignFinal(&md_ctx, sigbuf, &siglen, pkey);

Looks like some magic is used to get pkey, I think that's what I'm missing.
See php_openssl_evp_from_zval() in PHP's ext/openssl/openssl.c.

I've tried the following:
  key = M2Crypto.EVP.load_key(keyfile, lambda x: passphr)
  hmac = M2Crypto.EVP.HMAC(key, 'sha1')
  hmac.update(message)
  hmac.final()

But this results in:
File "/usr/lib/python2.4/site-packages/M2Crypto/EVP.py", line 39, in 
__init__
  m2.hmac_init(self.ctx, key, self.md)
  TypeError: expected a readable buffer object
  Segmentation fault

Unfortunately M2Crypto documentation is practically nonexistent..

I think basicly my question is: how do I extract the key from a private
key in M2Crypto?

Sounds great!

No, I get this:
AttributeError: PKey instance has no attribute 'sign_init'

Great! I was using 0.13.1 from both Debian en Ubuntu and I thought no
further development was done on it..

It would be nice to get this version into Debian.
