Class StrongDecimalNumberEncryptor

java.lang.Object

org.jasypt.util.numeric.StrongDecimalNumberEncryptor

All Implemented Interfaces:

DecimalNumberEncryptor

public final class StrongDecimalNumberEncryptor
extends Object
implements DecimalNumberEncryptor

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

This class internally holds a StandardPBEBigDecimalEncryptor 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(BigDecimal) or decrypt(BigDecimal) operations.

This class is thread-safe.
