Description

TIDEADecryptStream is a stream which decrypts anything that is read from it using the IDEA mechanism. It reads the encrypted data from a source stream and decrypts it using the CipherIDEA algorithm. It is a read-only stream: it is not possible to write data to this stream.

When creating a TIDEADecryptStream instance, an IDEA decryption key should be passed to the constructor, as well as the stream from which encrypted data should be read written.

The encrypted data can be created with a TIDEAEncryptStream encryption stream.
