Encryption Algorithm in SSFA vs. STRUST


I am doing the configuration for encrypting credit card using Cryptolib as per SAP Note: 662340.

One think I noticed is that in SSFA transaction we have to specify the encryption alogorithm (the choices are DES-CBS and TRIPLE-DES). We have to also specify the Private Address book (name of the .PSE file) here.

Then in STRUST transaction we create a PSE file (with the same name as mentioned in SSFA) and again have to select the encryption algorithm (the choices are RSA and DSA) with key length.

So, I am not sure which algorithm SAP is using to is SSFA or the one specified in STRUST?

Any help would be highly appreciated.

    Hi Paresh,

    SSF makes use of hybrid encryption, which consists of a symmetric algorithm like DES-CBS or TRIPLE-DES and an asymmetric algorithm like RSA. Note that the DSA algorithm can't be used for encryption.

    Best regards,
