Description

TIDEAEncryptStream is a stream which encrypts anything that is written to it using the IDEA mechanism, and then writes the encrypted data to the destination stream using the CipherIDEA algorithm. It is a write-only stream: it is not possible to read data from this stream.

When creating a TIDEAEncryptStream instance, an IDEA encryption key should be passed to the constructor, as well as the stream to which encrypted data should be written.

The resulting encrypted data can be read again with a TIDEADecryptStream decryption stream.
