The iv is prefixed to the encrypted data
aesCBC128Encrypt will create a random IV and prefixed to the encrypted code.
aesCBC128Decrypt will use the prefixed IV during decryption.

PHP has no support for running code concurrently unless you install extensions such as pthread. This can be sometimes bypassed by using proc_open() and stream_set_blocking() and reading their output asynchronously.
If we split code into smaller chunks we can run it as multiple suprocesses. Then usi...
There are very good configurations to force typings and get more helpful errors which are not activated by default.

The point about temporary tables is that they're limited to the scope of the connection. Dapper will automatically open and close a connection if it's not already opened. That means that any temp table will be lost directly after creating it, if the connection passed to Dapper has not been opened.

Random mask will show a rundom number from the specified range instead of the actual value:

You can grant in-privileged users right to see unmasked values using the following statement:

Password Based Key Derivation can be used both for deriving an encryption key from password text and saving a password for authentication purposes.
There are several hash algorithms that can be used including SHA1, SHA256, SHA512 which are provided by this example code.

Spring is a framework, which provides bunch of classes, by using this we don't need to write boiler plate logic in our code, so Spring provides an abstract layer on J2ee.
