RE: Database Encryption and PCI issue.

[Craig Wright <Craig.Wright () bdo com au>]

The DBMS_OBFUSCATION_TOOLKIT package only supports MD5 hashing. No SHA1.

The DBMS_CRYPTO package supports MD5, SHA-1, MD4, hashing and also HMAC_MD5, HMAC_SH1 keyed hashing algorithms.

The issues is Oracle 9i. It supports MD5 and NO more. So no SHA1 in Oracle 9i. Upgrade to 10g and you get the added 
crypto package (DBMS_CRYPTO).

Also with 9i, there is no padding, only CBC mode and support for RAW, VARCHAR2 database types (i.e. no CLOB, BLOB).

Hello, Mohamed Farid!

What is problem to use hash value (e.g. SHA1 ) of PIN as PK?
