Encrypt Password in Configuration Files?
A simple way of doing this is to use Password Based Encryption in Java. This allows you to encrypt and decrypt a text by using a password. This basically means initializing a javax.crypto.Cipher with algorithm “AES/CBC/PKCS5Padding” and getting a key from javax.crypto.SecretKeyFactory with the “PBKDF2WithHmacSHA512” algorithm. Here is a code example (updated to replace the less secure MD5-based variant): One problem remains: Where … Read more

No. If estimated size of the data is larger than maxResultSize given job will be aborted. The goal here is to protect your application from driver loss, … Read more
Environment variable to control java.io.tmpdir?
Hmmm — since this is handled by the JVM, I delved into the OpenJDK VM source code a little bit, thinking that maybe what’s done by OpenJDK mimics what’s done by Java 6 and prior. It isn’t reassuring that there’s a way to do this other than on Windows. On Windows, OpenJDK’s get_temp_directory() function makes a Win32 API … Read more
