-Oracle-Application-Level-Encryption-Decryption
-==============================================
 
-Oracle based application level Encryption and Decryption utilities for 10g and 11g(AES enabled)
-
-Ref: http://devopam.github.io/Oracle-Application-Level-Encryption-Decryption/
-
-1. Please place all the source code files provided in one single location ( preferably a single directory )
-a. error_log.ddl
-b. ex_crypto_pkg.ddl
-c. ex_crypto_pkg_body.ddl
-d. run_before_install.sql
-
-2. Please run the file : run_before_install.sql to verify that there is no conflict with an existing object in your database.
-If there are any objects in the list generated by script then you may wish to manually inspect the DB object(s) before executing 
-the next steps to avoid any data / object loss.
-
-3. Compile the script : error_log.ddl 
-The script expects tablespace named 'ext_data_ts' to be present and accessible. 
-Please replace the same with appropriate tablespace name OR remove the tablespace clause as applicable.
-
-e.g : from unix prompt - after logging into oracle , fire the command
-@error_log.ddl
-
-4. Compile the script : ex_crypto_pkg.ddl
-
-5. Execute wrap utility for hiding the  : 
-E.g : In a unix box , which has oracle connectivity defined (i.e. $ORACLE, $TNS_HOME etc. are defined) execute this command
-wrap iname=ex_crypto_pkg_body.ddl
-
-This will generate a file named : ex_crypto_pkg_body.plb
-
-Compile this file as usual : 
-E.g : from unix prompt - after logging into oracle , fire the command
-@ ex_crypto_pkg_body.plb
-
-6. Verify that the encryption package is working properly by using the sample below:
-
-SELECT ex_crypto.f_decrypt(ex_crypto.f_encrypt('Exilant Technologies Pvt. Ltd.')) FROM DUAL;
-
---This command will validate both encryption and decryption functions. For detailed function list , please refer to Usage Instructions.
-
-7. Delete the source file(s) :
-a. ex_crypto_pkg.ddl
-b. ex_crypto_pkg_body.ddl
-c. ex_crypto_pkg_body.plb
-
-8. Uninstall process:
-Please ensure that the error log table and logging procedure don't have any other dependency or are getting used anywhere.
-Also, it is suggested to take a backup of error log table , in case the error logging module is to be used separately.
-
-Compile the script :
-uninstall_encryption.sql 
-
-This will systematically remove all components installed as part of the crypto module.
