In the process, we add a "randfunc" parameter to
- Crypto.Cipher.PKCS1_OAEP.new()
- Crypto.Cipher.PKCS1_v1_5.new()
- Crypto.Signature.PKCS1_PSS.new()
to set the PRNG used by each algorithm.
Previously, the PRNG was taken from the RSA key itself.
This patch does a few things to simplify the public key classes
(RSA, DSA and ElGamal):
* It removes the Crypto.PublicKey.pubkey module. The 3 classes
do not have an ancestor anymore.
* Methods sign(), verify(), encrypt(), and decrypt() are removed.
* Methods blind() and unblind() are removed.
* Methods can_sign() and can_encrypt() are removed.
* The 3 classes cannot be pickled anymore.
* Add table to Crypto.Util package docs
* Clarify that PKCS#1v1.5 encryption only works on byte strings
* Clarify that padding is ignored by Cipher classes
* Clarify that block encrypt() and decrypt() do not respectively
add and remove any padding.
* Clarify what the 'overflow' parameter does (that is, nothing)
to the Crypto.Util.Counter class.
Objects used by PKCS#1 modules were treated as private,
and therefore ignored by epydoc.
Replaced SHA module with None as PBKDF1 default parameter value, because it was
not displayed nicely by epydoc. Default value is assigned in the body.
