Oracle DBMS_CRYPTO supports the National Institute of Standards and Technology (NIST) approved Advanced Encryption Standard (AES) encryption algorithm. Oracle DBMS_CRYPTO also supports Data Encryption Standard (DES), Triple DES (3DES, 2-key and 3-key), MD5, MD4, and SHA-1 cryptographic hashes, and MD5 and SHA-1 Message Authentication Code (MAC). DBMS_CRYPTO can encrypt most common Oracle datatypes including RAW and large objects (LOBs), as well as BLOBs and CLOBs. Performance of Oracle's dbms_crypto.hash function for SHA-1. Ask Question Asked 11 years, 8 months ago.

It provides support for several industry-standard encryption and hashing algorithms, including the Advanced Encryption Standard (AES) encryption algorithm. The DBMS_CRYPTO package enables encryption and decryption for common Oracle datatypes, including RAW and large objects ( LOB s), such as images and sound. Specifically, it supports BLOB s and CLOB s. In addition, it provides Globalization Support for encrypting data across different database character sets.
