ABSTRACT:
A method and apparatus for creating a secure script. Executable commands in the script are hashed, and the hashed values for the commands are encrypted and appended to the script. Before executing the script, a hashed value for each executable command in a script is computed and the encrypted hashed value appended to the script for each executable command in the script is decrypted to obtain a decrypted hashed value for each executable command in the script. The hashed value and the decrypted hashed value for each executable command is compared, and if the values are the same, the command is executed.
