org.bouncycastle.crypto.io.CipherInputStream
A CipherInputStream is composed of an InputStream and a BufferedBlockCipher so that read() methods return data that are read in from the underlying InputStream but have been additionally processed by the Cipher. The Cipher must be fully initialized before being used by a CipherInputStream.
For example, if the Cipher is initialized for decryption, the CipherInputStream will attempt to read in data and decrypt them, before returning the decrypted data.
