There are two ways of encrypting-decypting the pl/sql block in Oracle8i/9i.
--> U can use WRAP utility. But that is one way process. It only encrypts the particular block but once encrypted, it cant be decrypted. It is usually used in the Production Release.
--> U can use DBMS_OBFUSCATION_TOOLKIT package to encrypt/decrypt the particular pl/sql block. It is two way process. But if u want to encrypt an already encrypted file by the same package, it will throw an error. It uses DSA algo and key length is 56 bit. Just chesk the URL to know more about DBMS_OBFUSCATION_TOOLKIT
