Amit,

Is the parameter only being passed around within Blue Prism or is to be passed by/to an outside application? If it's coming from an outside application then that application would handle the encryption and what you would need to do in Blue Prism is decrypt it. One possible option would be to leverage a code stage in a VBO and use the various encryption libraries available in the .NET framework.

Cheers,

@ewilson - I was also trying to encrypt and decrypt data using VBO - encryption. I copied the key from system tab as appearing there, however VBO is not accepting the key. I also tried to encrypt the Key in WQ with key encryption checkbox in system tab when creating WQ. However after selecting that as well, the key column actual value is visible in control room and not encrypted value. ​

Hi Eric, 

Thanks for your reply, 

Input parameter passed from an outside application, I have used RijndaelManaged() for Encryption & Decryption and it is working fine for me.
Thanks for your valuable input, Helped me lot. 🙂

@AmitChauhan - glad to hear you have this running now.

@Mayank Goyal​​ - the encryption scheme used by the encryption VBO is Triple DES which uses a 192 bit key. It's actually an older encryption schema and the VBO should be updated to use something newer. If you want to use the VBO as-is, you need to generate a 192 bit key as opposed to the 256 bit key generated by AES and Rijndael.

@ewilson - Thanks a lot for your response. Please suggest if VBO will be updated in near future to fix it? ​

@Mayank Goyal I have asked a member of my team to work on updating the VBO. Once he's finished, it will be posted to the Digital Exchange.

I'll post an update here when that's complete.

Hi Mayank,

I have updated existing VBO with 256AES encryption, If you want i can share it with you.
Updated VBO is working fine with 256AES -Key,  You can use it in your process as per your need.


Thanks
