AES Encryption

Trying to use AES encryption for a url. I have a plain text string, a 16-byte key and a initialization vector. I am trying to match a C# implementation that uses RijndaelManaged class with a BlockSize = 128, Mode = CipherMode.CBC, Padding = PaddingMode.PKCS7. The output of the $SYSTEM.Encryption.AESCBCEncrypt(text,key,IV), doesn't match what is coming out of C#. All inputs into the $SYSTEM.Encryption.AESCBCEncrypt(text,key,IV) are converted to UTF8 as in the documentation.

Hi,

I have a situation where I write a character stream to a file. The file content gets signed and the signature is sent to a service provider together with the file content.

The signing is done using openssl.

This works perfectly on a dev PC, which is runnning Windows and has a little-endian architecture.

The problem is as soon as I do this on the server, which has a big-endian architecture, the signed value is incorrect according to the service provider.

The content is signed using RSA SHA256 with PSS padding.

I'm currently re-engineering an application from CSP pages directly accessing COS Methods, to an Angular/Material front end accessing a REST DAL. Both the Angular front end and REST services are hosted from the same Caché instance and the same namespace, but the REST services have their own CSP application, with all calls being routed through a Dispatch class.

Hi,

I have a client who is considering encryption options in order to comply with a tendering requirement.

Were they to encrypt the production database then what would be a reasonable expectation forthe impact on message throughput. Or possibly more easily answered: what would be the expected impact be on I/O rate and CPU utilization. Are there any benchmarks to which could support an estimate ?

How would this compare with plan B: to use disk encryption ?

Thanks
