FTPs and supported cipher

[Former Member]

Hi,

I'm implementing a connection with a supplier using FTPs. They need to know what ciphers PI supports. According to SAP 'The application of FTPS follows specification RFC 4217'. That specification doesn't describe the cipher-suites that can be used. I've searched sap notes and can't find anything that describes the ciphers used.

Does anyone know what ciphers are available within PI, I'm on PI 7.0(2004s) SP13.

Thanks in advance.

Hello Rob

Firstly, you need to have the SAP Java Cryptographic library installed. See the link:

SAP Java Cryptographic Toolkit and Policy Jurisdiction Files

http://help.sap.com/saphelp_nw04s/helpdata/en/8d/cb71b8046e6e469bf3dd283104e65b/content.htm

You can also try checking in the Visual Administrator

VisualAdmin

-> Services

-> "Security Provider"

-> "Cryptography Providers"

I think the information on what cipher suites are used is stored in the SSL Provider Service -

http://help.sap.com/saphelp_nw04s/Helpdata/EN/8a/a7ca5cf214d246be16affcdef1ff03/content.htm

As a test you can select under the Dispatcher -> Services the SSL Provider and start the service. You now should get all the supported Cipher Suites.

Mark,

Thanks for the response. We have the tookit installed and are currently supporting secure connections over HTTP and FTP. My problem is that a client needs to know the ciphers available before they will move forward. The link you supplied is useful but SAP don't actually say what ciphers they use. The following comment appears in the help document

DES, RC4, and others

SAP then suggest I refer to Netscape for details. I'm hoping this is documented somewhere but knowing SAP it probably isn't. I may just have to engage 5 consultants for 2 weeks to find out

Mark,

Thanks - the information was available through visual administrator as you suggested. I also found it here.
