TLS v1.2 support in Caché


What version of Caché supports TLS v1.2? 


Caché 2015.2 announced support for TLS v1.1 and v1.2.  In this version, the SSL/TLS configuration page provides checkboxes for TLS v1.1 and v1.2, which allows the versions to be configured individually.  This allows sites to, for example, require TLS v1.2 only.

Additionally, some earlier versions of Caché provide undocumented support for TLS v1.1 and v1.2, specifically Caché 2014.1.3 and above and 2015.1, on Windows, Linux and Unix.

Is there a way for us to restrict user's ODBC permissions based on what program they're running on a client?

For example, we have some older Windows apps (.exe) that are a regular part of our software package which require the user to be able to select, insert, update, and delete. Some of our users are also using other third-party apps to connect (mostly reporting tools) but we only want them to be able to select unless we've approved the exe. Is there a way to do that?

These are not applications that were developed using CacheDirect.

There's an easy new way to add certificate authority (CA) certificates to your SSL/TLS configurations on InterSystems IRIS 2019.1 (and 2018.1.2) on Windows and Mac.  You can ask IRIS to use the operating system's certificate store by entering:


in the field for "File containing Trusted Certificate Authority X.509 certificate(s)".   Here's an image of how to do this in the portal:

I am sure I came across this in the past with Cache and just saw this again in IRIS.

When rebuilding or swapping a DAT file for a database it retains the Resource of the DAT file, not the Resource of the Database it is being used for.

For instance, if I have a local Database called APP with a resource %DB_APP and I want to refresh the data from another Database called TEST that has a Resource %DB_TEST I can just copy the DAT file from the TEST folder to the APP folder.

3DES support

There are several ways of classifying cryptographic algorithms: 1) Secret Key Cryptography (SKC) - Uses a single key for both encryption and decryption. It is also called symmetric encryption. Primarily, it was used for privacy and confidentiality; 2) Public Key Cryptography (PKC) - Uses one key for encryption and another one for decryption. It is also called asymmetric encryption.

Oauth 1.0 library

I am in need of a routine or class method to generate an Oauth 1.0 signature.  I was about to code this myself, but thought to check first to see if anyone has already done this and is willing to share.

Thanks in advance for any help.

I was wondering if there was a certain procedure or documentation on securing (Https://) the Web Portal into IRIS/Ensemble?

Currently we are using LDAP Delegated Authentication to access the Web Portal using LDAP. However as more and more emphasis is put on securing applications within networks, I can see Management/Security asking us to make sure that the web portal is more secure.

SNN Encryption

I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.

For what I've seen my options are: 

- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.

- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.

Leveraging the Audit database

The InterSystems IRIS has a great audit system. It is responsible for auditing system events, but you can use it to audit your applications (great feature).

The audit system is based into event concept. The events can occur with IRIS or in an application. So, we have two type of events to the audit system:

1. System events: events occured into the InterSystems IRIS components (database, interoperability, analytics and core);
