Class KeyEncryptBase

object --+
         |
        KeyEncryptBase

Known Subclasses:: KeyEncryptCipher, ZipKeyEncryptCipher

Abstract base class used for extending the EncryptBase class for encryption of packets using public key encryption algorithms. This class support writing stream meta-information for public key streams.

Method Summary
	`__init__(self, enc_keys, sign_keys)` Initialize the key encryption class by assigning the list of encryption and signature keys that are used to encrypt/sign the stream.
a new object with type S, a subtype of T	`__new__(S, ...)`
	`_encryptionHeader(self)` Write the encryption header.
	`_encryptionSignature(self)` Write out the key signatures for this stream.

Class Variable Summary
`bool`	`_showpassword`

Method Details

init(self, enc_keys=[], sign_keys=[])
(Constructor)

Initialize the key encryption class by assigning the list of encryption and signature keys that are used to encrypt/sign the stream.

new(S, ...)

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

_encryptionHeader(self)

Write the encryption header. This header contains the password in encrypted form for all keys for which the stream is to be encrypted. This method is called from EncryptBase initialization.

_encryptionSignature(self)

Write out the key signatures for this stream. The key signatures are all read on decryption, and checked against the stream.

Class Variable Details

_showpassword

Type:

bool

Value:

False
