org.jasypt.exceptions.EncryptionOperationNotPossibleException

问题

I am using Jasypt-1.9.0 with Spring 3.1 and Hibernate 4.0.1. I have a requirement in my application to connect to database whose password(root) is stored in the encrypted form in the property file within the application.

I looked online and found the way with following links:

http://www.jasypt.org/spring31.html
http://www.jasypt.org/hibernate.html
http://www.jasypt.org/encrypting-configuration.html

I have done following steps and configuration for my requirement:

Added jasypt-1.9.0 and jasypt-hibernate4-1.9.0 in build path.
Added following in my dispatcher-servlet file:

< bean id="propertyConfigurer" class="org.jasypt.spring31.properties.EncryptablePropertyPlaceholderConfigurer">

   < constructor-arg ref="configurationEncryptor" />
   < property name="locations">
     < list>
       < value>classpath:database.properties< /value>
     < /list>
   < /property>
 < /bean>

 < bean id="configurationEncryptor"
     class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
   < property name="config" ref="environmentVariablesConfiguration" />
 < /bean>

 < bean id="environmentVariablesConfiguration"
class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
< property name="algorithm" value="PBEWithMD5AndDES" />
< property name="passwordEnvName" value="APP_ENCRYPTION_PASSWORD" />
</bean>

Using CLI tool of Jasypt 1.9.0, i have generated the password below(attached snapshot of CLI)

- Added a new Environment Varibale as APP_ENCRYPTION_PASSWORD with value as root

Added the encrypted password in database.properties file

db.driverClassName=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/db1
db.username=root
db.password=ENC(bmfeQmgP/hJrh+mj6NANKA==)

Now if i run my application, following exception appears:

org.jasypt.exceptions.EncryptionOperationNotPossibleException
    at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.decrypt(StandardPBEByteEncryptor.java:981)
    at org.jasypt.encryption.pbe.StandardPBEStringEncryptor.decrypt(StandardPBEStringEncryptor.java:725)
    at org.jasypt.properties.PropertyValueEncryptionUtils.decrypt(PropertyValueEncryptionUtils.java:72)

回答1:

The question is most probably out of date, but for future seekers... EncryptionOperationNotPossibleException is a general exception thrown by jasypt to mask other possible exceptions. This exception can occur when:

your jdk does not have the JCE unlimited strenght installed (most common case)
you had some data in the database that was encrypted before with other password
you had some data in database that were not encrypted before and you added encryption to some field
jasypt failed to decrypt the encrypted value from db because of some strange corruption of data
many many others, you just need to debug to find out the real cause..

I also experienced similar issue when encrypting property file values. I encrypted values in my local Windows machine and tried to deploy in Linux box but JRE versions were different, therefore encrypted values could not be decrypted. But I encrypted the values in Linux machine and decryption was successful.
