Hi all, I am new to hashing/encypting data. Is there a non-reversible hashing function? I need to hash confidential customer information. I am using Enterprise Guide 7.1. Therefore functions in any version after that wouldn't be accessible for me. Thank you!

See if the SHA256 function is available.

Since Enterprise Guide is not my strong point and know that the 7.versions are old-ish I'll leave it up to you to see if available.

 

Or run some code like:

data _null_;
   y=sha256('abc');
   z=sha256('access method');
   put y=$hex64.;
   put z=$hex64.;
run;

and see if you get an error. The output in the log varies depending on OS.

The MD5 function is another way of hashing that is irreversible and converting it to hex makes it even harder.

MyKeyHashed = put(md5(cats('MyHashedKey',MyKeyVar)),$hex10.);

Enterprise Guide is a dumb interface.

It doesn't run any code.

The SAS version to which you connect from EG is what validates what you can run.

Function SHA256 has been around for a while, so you probably can run it.

What @ChrisNZ wanted to point out is, that the version of Enterprise Guide is hardly relevant when talking about functions. Important alone is the version of the executing sas-environment. You can check that version by executing

%put &=SysVLong;
