Methods defined here:
- has_private(self)
- Return a Boolean denoting whether the object contains
private components.
- publickey(self)
- Return a new key object containing only the public information.
- size(self)
- Return the maximum number of bits that can be handled by this key.
Data and other attributes defined here:
- keydata = ['p', 'g', 'y', 'x']
Methods inherited from Crypto.PublicKey.pubkey.pubkey:
- __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)
- __ne__(self, other)
- __ne__(other): 0, 1
Compare us to other for inequality.
- __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.
- 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.
- 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.
