Depends on the used encryption algorithm. Some encrypt on a per-byte (or |

per-word) basis, others use a chaining method which makes all bytes |

In general, it's recommended to assume that one faulty bit results in a |

complete loss of all information. This might not always be true, but from a |

security PoV you'll always have to assume the worst. |
