They can also be used by a single user to determine if her files have been altered, perhaps by a virus. A user could compute the MAC of his files and store that value in a table. This book includes scripts and tools to hypercharge Oracle 11g performance and you can buy it for 30% off directly from the publisher. Oracle has provided the DBMS_CRYPTO package for data encryption starting from the version 10gR1 as an attempt to replace its predecessor, the DBMS_OBFUSCATION_TOOLKIT package. EDB Postgres Advanced Server v9.5: EDB Postgres Advanced Server (EPAS) builds on open source PostgreSQL, the world's most advanced open-source database management system, adding powerful enterprise-class functionality. DBMS_CRYPTO provides various algorithms for data encryption or decryption such as DES (Data Encryption Standard), 3DES (Triple DES), and AES (Advanced Encryption Standard), and supports several block chaining or padding methods.

Problem Definition: Data need to keep in database in encrypted way, only application user will be able to encrypt and decrypt data when needed. Anyone having DBA privileges should not be able to see the source code for security purpose, source code should be hidden. Feel the difference between PL/SQL and SQL. SQL statement can reference stored/package functions.

DBMS_CRYPTO provides an interface to encrypt and decrypt stored data, and can be used in conjunction with PL/SQL programs running network communications.
