TRANSLATOR - Encryption Decryption Package for Oracle DB

TRANSLATOR - Encryption Decryption Package for Oracle DB

In cryptography, encryption is the process of transforming information (referred to as plain-text) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as cipher-text). In many contexts, the word encryption also implicitly refers to the reverse process, decryption (e.g. “software for encryption” can typically also perform decryption), to make the encrypted information readable again (i.e. to make it un-encrypted).

TRANSLATOR provides an interface to encrypt and decrypt stored data, and can be used in conjunction with PL/SQL programs running network communications. It provides support for several industry-standard encryption, including the Advanced Encryption Standard.
