    this performs a specific DES-CBC encryption implementation
    as needed by the Oracle10 hash. it probably won't be useful for
    other purposes as-is.

    input value is null-padded to multiple of 8 bytes.

    :arg key: des key as bytes
    :arg value: value to encrypt, as bytes.
    :param iv: optional IV
    :param pad: optional pad byte

    :returns: last block of DES-CBC encryption of all ``value``'s byte blocks.

RS(sûThis class implements the password hash used by Oracle up to version 10g, and follows the :ref:`password-hash-api`.

    It does a single round of hashing, and relies on the username as the salt.

    The :meth:`~passlib.ifc.PasswordHash.hash`, :meth:`~passlib.ifc.PasswordHash.genhash`, and :meth:`~passlib.ifc.PasswordHash.verify` methods all require the
    following additional contextual keywords:

    :type user: str
    :param user: name of oracle user account this password is associated with.

sEThis class implements the Oracle11g password hash, and follows the :ref:`password-hash-api`.

    It supports a fixed-length salt.

    The :meth:`~passlib.ifc.PasswordHash.using` method accepts the following optional keywords:

    :type salt: str
    :param salt:
        Optional salt string.
        If not specified, one will be autogenerated (this is recommended).
        If specified, it must be 20 hexadecimal characters.

    :type relaxed: bool
    :param relaxed:
        By default, providing an invalid value for one of the other
        keywords will result in a :exc:`ValueError`. If ``relaxed=True``,
        and the error can be corrected, a :exc:`~passlib.exc.PasslibHashWarning`
        will be issued instead. Correctable errors include
        ``salt`` strings that are too long.
