Class StrongIntegerNumberEncryptor

java.lang.Object

org.jasypt.util.numeric.StrongIntegerNumberEncryptor

All Implemented Interfaces:

IntegerNumberEncryptor

public final class StrongIntegerNumberEncryptor
extends Object
implements IntegerNumberEncryptor

Utility class for easily performing normal-strength encryption of BigInteger objects.

This class internally holds a StandardPBEBigIntegerEncryptor 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(BigInteger) or decrypt(BigInteger) operations.

This class is thread-safe.
