[pycrypto] RSA importKey

[Legrandin]

Hi Francois,

importKey was included in pycrypto 2.2. Try to print Crypto.__version__
to see which library your interpreter is picking up (most likely an
older one).

RSA in pycrypto currently uses no padding: it directly carries out the
exponentiation. Last year I created a patch to pycrypto 2.1 to support PKCS#1 v1.5
padding. You can find it here https://bugs.launchpad.net/pycrypto/+bug/502291 .
BTW, PKCS#5 is not applicable to RSA.
