Package g4ds :: Package algorithms :: Module algorithminterface :: Class AlgorithmInterface

[show private | hide private]

Class AlgorithmInterface

Known Subclasses:: AlgorithmImplementation, AlgorithmImplementation

Provides a common interface for all implementations for algorithms.

Method Summary
	`__init__(self, name)` Just ot set up the name of the implementation.
	`createKeyPair(self, bitlength)` Creates a key pair for the algorithm.
`String`	`decrypt(self, ciphertext, keyst)` Decrypts the ciphertext.
`String`	`encrypt(self, plaintext, keyst)` Encrypts the plain text.
	`getName(self)` GETTER
	`getPublicKey(self, privateKeySt)` Returns the public part of the key pair.
	`setKeyPair(self, key)` SETTER
`String`	`signMessage(self, message, keyst)` Provides a signature for the given message.
`Boolean`	`validate(self, message, signature, keyst)` Verifies, whether the exactly this message has been signed with the corresponding private key for this public key.

Instance Variable Summary
`String`	`_name`: Name of the Implementation

Method Details

init(self, name)
(Constructor)

Just ot set up the name of the implementation.

createKeyPair(self, bitlength=None)

Creates a key pair for the algorithm.

decrypt(self, ciphertext, keyst=None)

Decrypts the ciphertext.

Returns:: The plain text
(type=String)

encrypt(self, plaintext, keyst)

Encrypts the plain text.

Returns:: The corresponding cipher text
(type=String)

getName(self)

GETTER

getPublicKey(self, privateKeySt=None)

Returns the public part of the key pair.

setKeyPair(self, key)

SETTER

signMessage(self, message, keyst=None)

Provides a signature for the given message.

Parameters:: message - Message to be signed (usually plain text)
(type=String); keyst - Private key to use for signing - if none given, the one stored in the instance will be used
(type=String)

Returns:: Corresponding Signature
(type=String)

validate(self, message, signature, keyst)

Verifies, whether the exactly this message has been signed with the corresponding private key for this public key.

Parameters:: message - Message, which was signed (usually plain text)
(type=String); signature - Signature, which was created for this message
(type=String); keyst - Public key - the corresponding private key must have been used for signing the message
(type=String)

Returns:: True, if this message has produced exactly this signature if the corresponding private key was used, otherwise false
(type=Boolean)

Instance Variable Details

_name

Name of the Implementation

Type:: String
