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.
