Health Insurance Claim Number (HICN) Validator for pre-15.5 via Custom Script?
I need a solution
Hello all,
I was curious if anyone has implemented effective HICN detection in DLP versions prior to 15.5? I know that 15.5 contains a Data Identifier for HICN, which contains an HICN-specific validator that “computes the checksum and validates the pattern against it.” However, I have a deployment on 15.0.1, and we likely won’t be able to upgrade for another year or so.
Has anyone had success implementing a Custom Script validator that can calculate the checksum and validate the pattern against it?
I realize this is a long-shot, but I wanted to throw it out there.
Thanks!
Nick

Re: CERT file is broken in 4.4.0 OVA
The Unity Simulator OVA is broken. On the top line of the .cert file, you’ll see this text:
SHA1(unfinished11186_OS-c4dev_PIE_2893R-4.4.0.1534750794.1534763221-VVNX_OVA_RETAIL.mf)= 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
There are 2 problems with this:
1. That’s way too long to be a sha1 checksum of the manifest file. (and indeed it’s not)
2. Look at the file name… it’s probably from some mid-level build, not a final release. (the folder is even called unfinished).
If you fix that line in the cert file, then it won’t validate out. If you remove the cert file, and re-compile the now un-signed OVA you have to use the “–allowExtraConfig” switch with ovftool to get Humpty-dumpty put back together again.
