Hello,

Can anyone tell me which encryption methods sap snc uses to encrypt data.

whenever snc/data_protection parameter is set to its highest value the data movement betwenn sap gui and abap system is secured (encrypted?)

which type of data protection (encryption?) methood is used?

can you direct me to an offical material of sap?

Al lot of information can be found here already

On http://service.sap.com/security > Security in Detail > Infrastructure Security you find an SNC-Guide which is also quite useful.

The FAQs about Secure System Management [https://www.sdn.sap.com/irj/sdn/security?rid=/library/uuid/0a03d9f4-0901-0010-60ba-b3a1b1d41e0c] explain, what cryptographic algorithms SAPcryptolib supports. This applies for SNC connections between SAP servers. For encryption of client-server communication, you need to look at the capabilties of SAP-certified SNC products, because SAPcryptolib cannot be used here.

Make sure that you think about compatibility of the client-server encryption library with SAPcryptolib, if you want to use SNC both between client-server and server-server encryption. My company has worked with customers that needed additional, stronger encryption and hashing algorithms and a SAPcryptolib-compatible product.

Short answer: Triple DES. Peter provided the long answer already .
