L_ENCRYPTION_TYPE := dbms_crypto. Oracle Database 11g introduces a number of nifty new features to improve the performance of PL/SQL code, but the most dramatic ones are native compilation and intra-unit inlining.

Plaintext is XORed with the previous ciphertext block before it is encrypted." and pad_pkcs5 - "Provides padding which complies with the PKCS #5: Password-Based Cryptography Standard".

Syntax The syntax for the NVL function in Oracle/PLSQL is: NVL ( string1, replacewith ) Parameters or Arguments string1 The string to test for a null value. G_CHARACTER_SET VARCHAR2(10) := 'A元2UTF8' Description The Oracle/PLSQL NVL function lets you substitute a value when a null value is encountered. Here's a packaged function (successful implementation) for encrypting passwords using ( DBMS_CRYPTO)- CREATE OR REPLACE
#Oracle plsql decode password
You should be storing password hashes (which you can also generate using the DBMS_CRYPTO package) which are non-reversible. The right answer, of course, would be to rearchitect the system so that you don't store the passwords at all. It's generally a lot easier to steal data from a database than it is to sniff data getting sent over the network in order to find a password. It's bad to send passwords unencrypted over the network but it is generally much worse to store unencrypted passwords in the database (or encrypted passwords if there is a decrypt method in the database that has access to the key to decrypt the data). Of course, if you write your own routines, assuming that you store the key in the database or somewhere the database has access to, you're not doing much for security. pick your encryption algorithm, your key, etc.). If you want to write your own functions to encrypt and decrypt data, you would simply want to call the DBMS_CRYPTO encrypt and decrypt methods with appropriate parameters (i.e.
