Re: how to set project configuration

Hi,

I am also stuck with 'error: Java property "jc.home" is not set.' error while creating an applet that uses Shareable interface.

I am currently running JC 3.0.4.

Re: The difference between SHA, AES and RSA algorithm?

SHA -> digital data one way hashing.
AES -> digital content confidentiality protection via data scrambling.
RSA -> digital data confidentiality protection via data scrambling and also digital identity attestation and digital content verification via digital signatures.
