RSA Encryption Through PGP module : SAP PI 7.31

[Former Member]

Hi Experts,

              In my project there is a requirement for PGP encryption for a file Scenario.

              I used the PGP module in the communication channel.

              And i was able to encrypt the file succesfully using the default encryption algorithm (CAST5),

              But the requirement in the scenario is to specifically use 'RSA' Encryption algorithm.

              I tried to change the algorithm for encryption in the parameter "encryptionAlgo" under the module configuration

              within the communication channel by specifying the value as "RSA", but am getting error "value not supported" in channel audit log.

              I searched in net, but not able to find any solution related to scenarios using RSA algorithm.

              Does PI 7.31 supports RSA algorithhm ?

              If yes, what is the right approach to implement it.

              Please help and provide your inputs on the same,

Thanks and Regards,

             Amit

RSA is not supported.

Try to negotiate on one of the following supported encryption algorithms:

AES_128

AES_192

AES_256

Blowfish

CAST5 (which is the default)

DES (not recommended as it's really week by todays standards)

3DES

Twofish

You can use RSA for the key generation and exchange though (and RSA is almost always just used for key generation as it's a lot slower than AES for example).

Hi Amit,

     The PI PGP Module does support RSA. You have to generate the keys based on the RSA. There is no separate algorithm called RSA for encryption.
