Methods defined here:

__eq__(self, other)
  `__eq__(other): 0, 1
  Compare us to other for equality.`

__getstate__(self)
  `To keep key objects platform-independent, the key data is
  converted to standard Python long integers before being
  written out. It will then be reconverted as necessary on
  restoration.`

__init__(self)

__setstate__(self, d)
  `On unpickling a key object, the key data is converted to the big
  number representation being used, whether that is Python long
  integers, MPZ objects, or whatever.`

blind(self, M, B)
  `blind(M : string|long, B : string|long) : string|long
  Blind message M using blinding factor B.`

can_blind(self)
  `can_blind() : bool
  Return a Boolean value recording whether this algorithm can
  blind data. (This does not imply that this
  particular key object has the private information required to
  to blind a message.)`

can_encrypt(self)
  `can_encrypt() : bool
  Return a Boolean value recording whether this algorithm can
  encrypt data. (This does not imply that this
  particular key object has the private information required to
  to decrypt a message.)`

can_sign(self)
  `can_sign() : bool
  Return a Boolean value recording whether this algorithm can
  generate signatures. (This does not imply that this
  particular key object has the private information required to
  to generate a signature.)`

decrypt(self, ciphertext)
  `decrypt(ciphertext:tuple|string|long): string
  Decrypt 'ciphertext' using this key.`

encrypt(self, plaintext, K)
  `encrypt(plaintext:string|long, K:string|long) : tuple
  Encrypt the string or integer plaintext. K is a random
  parameter required by some algorithms.`

has_private(self)
  `has_private() : bool
  Return a Boolean denoting whether the object contains
  private components.`

publickey(self)
  `publickey(): object
  Return a new key object containing only the public information.`

sign(self, M, K)
  `sign(M : string|long, K:string|long) : tuple
  Return a tuple containing the signature for the message M.
  K is a random parameter required by some algorithms.`

size(self)
  `size() : int
  Return the maximum number of bits that can be handled by this key.`

unblind(self, M, B)
  `unblind(M : string|long, B : string|long) : string|long
  Unblind message M using blinding factor B.`

validate(self, M, signature)
  `# alias to compensate for the old validate() name`

verify(self, M, signature)
  `verify(M:string|long, signature:tuple) : bool
  Verify that the signature is valid for the message M;
  returns true if the signature checks out.`
