Yes, it does.

Your CLASSPATH should contain jce.zip before any references to any JDK
zip file.

Note that you don't *need* to explicitly add any JDK zip file to your
CLASSPATH. A CLASSPATH like

% setenv CLASSPATH <your-JDK-directory>lib/jce.zip

is sufficient. The java and javac scripts will automatically get
the system classes.

FYI: We have rewritten JCE. The new JCE (1.2) will be provided
as a Java extension to JDK1.2. A beta release of JDK1.2 will
be made available very soon, and an early access version of JCE1.2
will be released at about the same time.

JCE1.2 includes:

DES (ECB, CBC, CFB, OFB)
DES-EDE (ECB, CBC, CFB, OFB)
PBE (PKCS#5 password-based encryption)
Diffie-Hellman key negotiation
Check out

http://java.sun.com/security/JCE1.2/earlyaccess/index.html
for the new JCE APIs.

Since JCE1.2 will be provided as a JAVA extension to JDK1.2 (and not
as a "drop-in" package as JCE1.1), the restrictions on CLASSPATH
mentioned above will no longer apply.

Thanks,

Jan
