如何用Cryptix.jar这个加密包里边的DES算法、CBC模式对字符串加密？

[maxy7809]

我需用用DES算法，CBC模式加密数据，可是总是不正确，加密后再解回来，结果就错了，请高人指点。
我是这样初始化的：
Cipher cryptor = Cipher.getInstance(Cipher.getInstance("DES", "Cryptix"),(Mode)Mode.getInstance("CBC", "Cryptix"),PaddingScheme.getInstance("PKCS#5"));
这个声明和Cryptix的doc里边有点区别，doc里边的第一个参数是：Cipher.getInstance("DES", "SUN")，这样执行的时候包错，说不存在SUN这个provider。

如果这样声明的话：Cipher cryptor = Cipher.getInstance("DES", "Cryptix");
结果是正确的，但是这样好像用的不是CBC模式，而是CFB模式。

怎样才能正确的时候CBC模式加密呢？

有没有在JDK1.3\jre\lib\security\java.security文件里加。
#
# This is the "master security properties file".
#
# In this file, various security properties are set for use by
# java.security classes. This is where users can statically register
# Cryptography Package Providers ("providers" for short). The term
# "provider" refers to a package or set of packages that supply a
# concrete implementation of a subset of the cryptography aspects of
# the Java Security API. A provider may, for example, implement one or
# more digital signature algorithms or message digest algorithms.
#
# Each provider must implement a subclass of the Provider class.
# To register a provider in this master security properties file,
# specify the Provider subclass name and priority in the format
#
# security.provider.<n>=<className>
#
# This declares a provider, and specifies its preference
# order n. The preference order is the order in which providers are
# searched for requested algorithms (when no specific provider is
# requested). The order is 1-based; 1 is the most preferred, followed
# by 2, and so on.
#
# <className> must specify the subclass of the Provider class whose
# constructor sets the values of various properties that are required
# for the Java Security API to look up the algorithms or other
# facilities implemented by the provider.
#
# There must be at least one provider specification in java.security.
# There is a default provider that comes standard with the JDK. It
# is called the "SUN" provider, and its Provider subclass
# named Sun appears in the sun.security.provider package. Thus, the
# "SUN" provider is registered via the following:
#
# security.provider.1=sun.security.provider.Sun
#
# (The number 1 is used for the default provider.)
#
# Note: Statically registered Provider subclasses are instantiated
# when the system is initialized. Providers can be dynamically
# registered instead by calls to either the addProvider or
# insertProviderAt method in the Security class.

#
# List of providers and their preference orders (see above):
#
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.rsajca.Provider

已经加了，结果还是不正确。如果不是用CBC mode，结果就是正确的，为什么啊？
