jasypt property placeholder not working - mule

Question

I have this properties file:
secret.key = ENC(foobar)
region = ABC
Then in the config.xml:
<spring:beans>
<encryption:encryptor-config id="eConf" password-sys-property-name="MULE_ENCRYPTION_PASSWORD" algorithm="PBEWithMD5AndDES" password="" />
<encryption:string-encryptor id="stringEnc" config-bean="eConf" />
<encryption:encryptable-property-placeholder encryptor="stringEnc" location="${env}.properties" />
</spring:beans>
But the property placeholders don't work, for example:
<sqs:config secretKey="${secret.key}" region="${region}"></sqs-config>
Does anyone know why?

Answer 1

Encrypted password needs to be write within ENC() function and should be encrypted.
Let's consider in properties file where password value is Login#123... Now the encrypted value in properties file will be :-
password=ENC(B0u7D8wLwq/ugin31KNpP78gBcLP7VIN)
Step1 :- We can generate Key using following commands in Command prompt of \jasypt-1.9.2\bin directory :- encrypt input="Login#123" password=sqlpassword algorithm=PBEWithMD5AndDES
Step2 :- In runtime Environment we need to give (Right click->Run As->Run Configuration->Environment) :- Variable :- MULE_ENCRYPTION_PASSWORD and Value:-sqlpassword
In your Mule config, you need configure it as following :-
<spring:beans>
<spring:bean id="environmentVariablesConfiguration" class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
<spring:property name="algorithm" value="PBEWithMD5AndDES"/>
<spring:property name="passwordEnvName" value="MULE_ENCRYPTION_PASSWORD"/>
</spring:bean>
<!-- The will be the encryptor used for decrypting configuration values. -->
<spring:bean id="configurationEncryptor" class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
<spring:property name="config" ref="environmentVariablesConfiguration"/>
</spring:bean>
<!-- The EncryptablePropertyPlaceholderConfigurer will read the -->
<!-- .properties files and make their values accessible as ${var} -->
<!-- Our "configurationEncryptor" bean (which implements -->
<!-- org.jasypt.encryption.StringEncryptor) is set as a constructor arg. -->
<spring:bean id="propertyConfigurer" class="org.jasypt.spring.properties.EncryptablePropertyPlaceholderConfigurer">
<spring:constructor-arg ref="configurationEncryptor"/>
<spring:property name="locations">
<spring:list>
<spring:value>conf/yourPropertyFile.properties</spring:value>
</spring:list>
</spring:property>
</spring:bean>
Then you can use encrypted values like :- ${password}

I had similar issue, i did configure everything as explained in Activemq web site . In my case issue was PropertyPlaceholderConfigurer bean was loaded for to load other properties before the EncryptablePropertyPlaceholderConfigurer bean. So remove PropertyPlaceholderConfigurer bean's if any just add EncryptablePropertyPlaceholderConfigurer bean even for other non-encrypted properties as explained in Activemq then it works fine.
