CRC-32 generator using ACL

[aleslie]

Does anyone know if it is possible to code the CRC-32 algorithm using ACL ?

Or is it best carried out using Java and then called from within the ACL.

Regards,

Hi Andy-



ACL is a fairly complete programming language, so I'm sure you could
code CRC-32 in it if you wanted to. OTOH, it's probably easier to just
tap into the java.util.zip package and use their implementation. If you
want to write most of your code in ACL and just invoke the java code for
this, you can bridge to java from ACL using the java_constructor(),
java_instance(), etc. functions in ACL.

If you want to be clever about things, I found this neat SHA1 implementation
in Javascript J It's not CRC-32 but SHA1 is probably safer in most
applications anyway, due to reduced likelihood of hash collision.
