System Password Encryption/Decryption

Oracle9i Application Server Wireless Edition Configuration Guide

The Wireless Edition database password for the repository is stored in clear text in 
the System.properties file by default. The password can be encrypted by running 
the following tool to modify the db.connect.string:

encryptPassword.sh WE_HOME/server/classes/oracle/panama/core/admin

Then set the following property in the System.properties file:

passwordEncrypted=true

The 

SystemPasswordEncryptionHook.class

 identifies the encryption algorithm. To 

provide extensibility, the class can be used to invoke a user’s algorithm in place of 
the default algorithm.

The default setting is:

locator.SystemPasswordEncryptionHook.class=

     oracle.panama.rt.common.SystemPasswordEncryption

To use an alternate encryption algorithm, implement the following interface:

public interface SystemPasswordEncryptionHook {

  /** Encrypts the text

    * @param text the text to be encrypted

    * @return the encrypted text

    */

public String encrypt(String text);

  /** Decrypts the encrypted text

    * @param encryptedText the encrypted text

    * @return the decrypted text

    */

public String decrypt(String encryptedText);

}

This allows you to replace the default algorithm, for example:

locator.SystemPasswordEncryptionHook.class=

     oracle.panama.MyEncryption
