File Information
Library: Crypto
Package: Cipher
Header: Poco/Crypto/CryptoStream.h
Description
This stream transforms all data passing through it using the given CryptoTransform.
Use a CryptoTransform object provided by Cipher::createEncrytor() or Cipher::createDecryptor() to create an encrypting or decrypting stream, respectively.
After all data has been passed through the stream, close() must be called to ensure completion of cryptographic transformation.
