                             ZipKeyEncryptCipher

Class which works similar to KeyEncryptCipher, but streams all data through zipping on writing, so that it is in effect "randomized" on writing.
Method Summary
  __init__(self, enc_keys, sign_keys, cipher_algo, cipher_mode, IV, hash_algo)
See the KeyEncryptCipher.__init__ function for an explanation of the parameters to pass to this function.
a new object with type S, a subtype of T __new__(S, ...)
  feed(self, data)
Feed data to the encryption. (inherited from EncryptBase)
  finish(self)
Finish the encryption stream. (inherited from EncryptBase)
  _checkInst(self)
Instance checking done by all functions of this class. (inherited from ZipEncryptStream)
  _CipherStream__getPass(self)
Retrieve the password this stream uses. (inherited from CipherStream)
  _encryptionEnd(self)
Write out the encryption end packet. (inherited from EncryptBase)
  _encryptionHeader(self)
Write the encryption header. (inherited from KeyEncryptBase)
  _encryptionRandom(self)
Write out the random first block of data. (inherited from EncryptBase)
  _encryptionSignature(self)
Write out the key signatures for this stream. (inherited from KeyEncryptBase)
  _feedEncrypt(self, data)
Feed data to the encryption, but zip it before feeding it. (inherited from ZipEncryptStream)
  _feedEncryptRaw(self, data)
Feed the passed in packet to the encryption, and return any available data which comes back from the encryption routine. (inherited from EncryptStream)
  _feedOutput(self, ptype, pdata)
Feed packet to the output stream. (inherited from OutputStream)
  _start(self, cipher_algo, cipher_mode, IV, password, hash_algo)
Start the encryption stream with the passed in parameters, and create the crypto objects needed for the stream. (inherited from CipherStream)
  _stop(self)
Stop the decryption by finalizing the zlib object. (inherited from ZipEncryptStream)
  _StreamBase__getData(self)
Retrieve the data from the output property as a string. (inherited from StreamBase)
  _writeOutput(self, data)
Append data to the output. (inherited from StreamBase)

Method Details

__init__(self, enc_keys=[], sign_keys=[], cipher_algo=3, cipher_mode=0, IV=None, hash_algo=5)
(Constructor)

See the KeyEncryptCipher.__init__ function for an explanation of the parameters to pass to this function.

__new__(S, ...)

Returns:
a new object with type S, a subtype of T
