Use Oracle wrap tool to encrypt code

Oracle provides wrap tools for encrypting procedure, function, and package.Source code.
However, the encryptedCodeThe decryption fails. Keep the source code safe!
Example:

1. Set Environment Variables
Add
Nls_lang = "simplified chinese_china". zhs16gbk export nls_lang
Run the following command to make the environment variable take effect:
Source. bash_profile
2. Export the source code file as P. SQL (it can include multiple processes, functions, packages, etc)
3. Generate the encryption code:
[Oracle @ jumper tools] $ wrap INAME = P. SQL oname = P. PLB
4. Create an encryption code:
SQL> set define off;
SQL> @ P. PLB
5. Test the encryption code
