From SAP PI 7.30 we call we a SOAP web-service over https. This service was running for a long time. The provider of the web-service upgraded their SSL certificates from SHA-1 signing algorithm to the stronger and more robust SHA-256. After that, we get the following error: iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: handshake. As said, just before the change the connection was working. I have added the required VeriSign CA root certificates to the Trusted CA's keystore within NWA. (VeriSign Class 3 Secure Server CA - G4 and G5) Something must be wrong. When I look into SXMB_MONI, I see something for which I don't know if it is related: encryptionAlgorithmEncryptionEncriptionSignature value DES_EDE3_CBC. I am not an expert in this, but could it be possible that this should be AES256-CBC? How to change that?
Any help or suggestion is welcome. My next step will be to install XPI Inspector to figure out what is wrong.
