An invalid-version error might occur when you use SAS/SECURE^™ software encryption with an HTTPS secure server to transfer SAS data sets. One particular error that is generated is as follows:

ERROR: An I/O error has occurred on file SDD.TEST4G.DATA 

Secure transmission of sensitive communication (such as payment transfers on corporate information systems) often use Hypertext Transfer Protocol over Secure Socket Layer (HTTPS), which is a Uniform Resource Identifier (URL) scheme.

In SAS code, the problem occurs when a Read process returns only part of a secure socket layer (SSL) header. SAS runs the header information through an encryption function to convert it from transport format to host format. However, the length is already in host format. This conversion fails on hosts where the transport and the host formats are not the same.

Currently, there is no solution or workaround for this problem.

Please contact SAS Technical Support for more information about accessing the hot fix for this issue.

Operating System and Release Information

For illustration purposese, the following code downloads a data set that generates the error code explained in this note. Note that you need to enter your own values for the following user-supplied values:

• path-to-your-secure-server
• server-name
• user-name password
• your-machine-name

All files that need to be pushed for this example reside in /sas/dev/mva-v920/tkext/src/tkessl.c.

libname sdd base "path-to-your-secure-server" server-name user="user-name" password="password";

%let thepc=your-machine-name;
signon thepc user="user-name" password="password";
rsubmit; 
   libname pc 'e:/testing/datasets' access=readonly;

   proc download inlib=pc outlib=sdd;
      select test;
      select test2;
   run;
endrsubmit;

libname pc server=thepc;

proc compare data=pc.test compare=sdd.test;

proc compare data=pc.test2 compare=sdd.test2;
