Abstract

The invention concerns a method for protecting a source code in semi-interpreted language. The invention is characterized in that said source code (11) being compiled in an octet-code (12), said method includes the following steps: encrypting said octet-code (12) with an encrypting algorithm, providing a machine (20) using said source code (11), the encrypted octet code (13) and the octet code of a decrypting classloader (14) adapted to decrypt said encrypted octet code (13) using a decryption key (K8) available on said user machine (20). The invention is useful for protecting source codes against pirated copying.
