Message level encryption/decryption

Hi all,

 

I have a system A that sends raw TCP/IP messages to another system B that also only receives TCP/IP messages.

 

System A has the ability of encrypting the messages (say, PGP) but system B cannot handle any sort of encryption mechanism.

 

There is a F5 between both systems.

 

I am wondering if in F5 I can create an iRule, or anything else, that would allow system A to encrypt the information, send it to F5, then F5 will decrypt it and send it to system B (via an IPSec VPN tunnel that has been established).

 

I also have the opposite flow. System B sends messages to F5, that would need to encrypt them and send it to system A.

 

Thank you Felipe

    Conceptually, yes. But what's the encryption used? Do the messages HAVE to be encrypted (The question seems a bit unsure) or will it work with an encrypted stream?

     

    If a stream encryption is OK, then you can do most of it OOTB without an iRule using just a TLS connection
