让 django-paypal 与 pycrypto 一起使用？

我想在 django-paypal 中使用按钮加密，但它需要 M2Crypto，而 M2Crypto 不会构建在 webfaction 服务器上。 Webfaction 的技术支持告诉我，系统上已经安装了 pycrypto，但我太笨了，无法从 M2Crypto 转换为 pycrypto。

谁能告诉我如何将以下内容转换为与 pycrypto 一起使用（如果可能）？这只是显示加密的一个小片段，如果需要，我可以发布整个函数。

    s = SMIME.SMIME()   
    s.load_key_bio(BIO.openfile(CERT), BIO.openfile(PUB_CERT))
    p7 = s.sign(BIO.MemoryBuffer(plaintext), flags=SMIME.PKCS7_BINARY)
    x509 = X509.load_cert_bio(BIO.openfile(settings.PAYPAL_CERT))
    sk = X509.X509_Stack()
    sk.push(x509)
    s.set_x509_stack(sk)
    s.set_cipher(SMIME.Cipher('des_ede3_cbc'))
    tmp = BIO.MemoryBuffer()
    p7.write_der(tmp)
    p7 = s.encrypt(tmp, flags=SMIME.PKCS7_BINARY)
    out = BIO.MemoryBuffer()
    p7.write(out)   
    return out.read()

I would like to use the button encryption in django-paypal, but it requires M2Crypto which will not build on webfaction servers. Tech support at Webfaction told me that pycrypto is already installed on the system, but I am too dumb to translate from M2Crypto to pycrypto.

Can anyone tell me how to convert the following to work with pycrypto (if possible)? This is just a small snip showing he encryption, I can post the entire function if needed.

    s = SMIME.SMIME()   
    s.load_key_bio(BIO.openfile(CERT), BIO.openfile(PUB_CERT))
    p7 = s.sign(BIO.MemoryBuffer(plaintext), flags=SMIME.PKCS7_BINARY)
    x509 = X509.load_cert_bio(BIO.openfile(settings.PAYPAL_CERT))
    sk = X509.X509_Stack()
    sk.push(x509)
    s.set_x509_stack(sk)
    s.set_cipher(SMIME.Cipher('des_ede3_cbc'))
    tmp = BIO.MemoryBuffer()
    p7.write_der(tmp)
    p7 = s.encrypt(tmp, flags=SMIME.PKCS7_BINARY)
    out = BIO.MemoryBuffer()
    p7.write(out)   
    return out.read()

我能够构建它。为了实现这一目标，您需要执行以下操作：

cat >> ~/.pydistutils.cfg << EOF
[build_ext]
include_dirs=/usr/include/openssl
EOF
easy_install-2.5 --install-dir=$HOME/lib/python2.5 --script-dir=$HOME/bin m2crypto

I was able to get it to build. Here is all you need to do to make it happen:

cat >> ~/.pydistutils.cfg << EOF
[build_ext]
include_dirs=/usr/include/openssl
EOF
easy_install-2.5 --install-dir=$HOME/lib/python2.5 --script-dir=$HOME/bin m2crypto
