Class StrongBinaryEncryptor

java.lang.Object

org.jasypt.util.binary.StrongBinaryEncryptor

All Implemented Interfaces:

BinaryEncryptor

public final class StrongBinaryEncryptor
extends java.lang.Object
implements BinaryEncryptor

Utility class for easily performing high-strength encryption of binaries (byte arrays).

This class internally holds a StandardPBEByteEncryptor configured this way:

• Algorithm: PBEWithMD5AndTripleDES.
• Key obtention iterations: 1000.

The required steps to use it are:

1. Create an instance (using new).
2. Set a password (using setPassword(String) or setPasswordCharArray(char[])).
3. Perform the desired encrypt(byte[]) or decrypt(byte[]) operations.

This class is thread-safe.
