Command line Jasypt client encryption 'Operation not possible'
Solution 1
- The Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy (small download) can enable the higher strength algorithms.
https://www.oracle.com/technetwork/java/javase/downloads/jce-all-download-5170447.html
FYI: JDK 9 and later ship with, and use by default, the unlimited policy files.
The unlimited policy files for earlier releases available above are required only for JDK 8, 7, and 6 updates earlier than 8u161, 7u171, and 6u181. On those versions and later the policy files are included, but not enabled by default.
See JDK-8170157 for details. https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8170157
- Another issue, could be that your
JAVA_HOME
environment variable points to an older Java version. Jasypt's bin/*.sh and *.cmd scripts uses$JAVA_HOME/bin/java
or%JAVA_HOME%\bin\java
if that environment variable exists.
Solution 2
I faced this problem because of some lack of information in the Jasypt CLI usage description.
The default generator to generate the initial value is NoIvGenerator
. For some/most algorithms the IV generated this way is not valid, so the error message above is displayed. You have to add the additional parameter ivGeneratorClassName=org.jasypt.iv.RandomIvGenerator
to make it work.

I am using Jasypt to store our database passwords in our hibernate config file in non-clear-text format.
Eg instead of
<property name="hibernate.connection.username">user1</property> <property name="hibernate.connection.password">password1</property>
I want something like
<property name="hibernate.connection.username">user1</property> <property name="hibernate.connection.password">ENC(0HY4F73HFPQ85CN)</property>
I am using the PBEWITHMD5ANDTRIPLEDES algorithm. I was reading up on it, and it seems that this may require installing a JCE, or a 'Jurisdiction Policy' extension. My question is, are these things already installed if I see this in my list of PBE Algorithms?
I ran the listAlgorithms.bat script:
C:\dev\jasypt-1.9.1\bin>listAlgorithms.bat DIGEST ALGORITHMS: [MD2, MD5, SHA, SHA-256, SHA-384, SHA-512] PBE ALGORITHMS: [PBEWITHMD5ANDDES, PBEWITHMD5ANDTRIPLEDES, PBEWITHSHA1ANDDESEDE, PBEWITHSHA1ANDRC2_40]
But when I try to encrypt my password, I get a very unhelpful error message:
C:\dev\jasypt-1.9.1\bin>encrypt.bat input=etrading_rw_123 password=encryptionkey algorithm=PBEWITHMD5ANDTRIPLEDES ----ENVIRONMENT----------------- Runtime: Sun Microsystems Inc. Java HotSpot(TM) Client VM 20.14-b01 ----ARGUMENTS------------------- algorithm: PBEWITHMD5ANDTRIPLEDES input: etrading_rw_123 password: encryptionkey ----ERROR----------------------- Operation not possible (Bad input or parameters)
If I run the same script with algorithm=PBEWITHMD5ANDDES, it works fine. Does the list of 'supported algorithms' actually mean 'algorithms that would be supported if you enabled them' rather than 'algorithms that are good to go'?
I am using Java version:
java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing)
