Class CryptInputStream

java.lang.Object

java.io.InputStream

java.io.FilterInputStream

de.mibos.commons.crypt.CryptInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class CryptInputStream
extends FilterInputStream

An input stream for the specified Crypt which decrypts a cipher input stream.
This is simply an extension to the standard CipherInputStream, which reads the initialization vector in the constructor. So both constructors may throw an IOException, if failing to read the initialization vector.

Constructor Detail

CryptInputStream

public CryptInputStream(@Nonnull
                Crypt crypt,
                @Nonnull
                InputStream input,
                @Nonnull
                CharSequence password)
                 throws IOException

An input stream for the specified Crypt which decrypts a cipher input stream.
This is simply an extension to the standard CipherInputStream, which reads the initialization vector in the constructor. So this constructor may throw an IOException, if failing to read the initialization vector.

Parameters:

crypt - the used Crypt object

input - the cipher input stream

password - the password

Throws:

IOException - IOException if failing to read the initialization vector

CryptoInitializationProblem - in case of a CryptoInitializationProblem problem
