Description
The TBlowFishDecryptStream provides On-the-fly Blowfish
decryption: all data that is read from the source stream is decrypted
before it is placed in the output buffer.
The source stream must be specified when the
TBlowFishDecryptStream instance is created. The Decryption
key must also be created when the stream instance is created, and must be
the same key as the one used when encrypting the data.
This is a read-only stream: it is seekable only in a forward direction, and data can only be read from it, writing is not possible. For writing data so it is encrypted, the TBlowFishEncryptStream stream must be used.
