Encryption in FIX

I have a query regarding encryption in FIX. When we specify that we are using PGP+DES+MD5 encryption method by saying 98=3 i.e. the EncryptMethod field of the LOGON message is sent as 3 does this mean that we are using PGP for encrypting the LOGON message only, DES for encrypting further messages and MD5 for message signature. Does this explanation also hold good when we choose PKCS+DES or PEM+DES+MD5 encryption method.

Thanks in advance

Yes.

Yes.

Lavanya,

You are probably referring to 98=5. The “PGP-DES-MD5 and PEM-DES-MD5 Overview” document in http://www.fixprotocol.org/specifications/TechDoc-InfoSecurity will provide you a general overview of the PGP-DES-MDS implmentation. Hope this helps.

Regards,

Chris
