Encrypt 15 digit number

I am looking for ideas on how to take a 15 digit positive number run an algorithm against it to produce another number that essentially encrypts it. There is not a need to decyprt the number back to its original.

Any thoughts or ideas?

Since there is no need to decrypt the number, you could just generate a random 15 digit number and use that.

Do you really care if it is related to the original?

In fact it is safer. Somebody could potentially determine your algorithm, and reverse engineer it.

Google "z/os cryptographic services". You'll get many hits.

It might already be installed and used in your shop.

Check with your z/OS Systems folks.

HTH....
