Encrypting License keys

[Rick Weiser]

Hi all,

Has anyone tackled encrypting a software license key?  If so, can you share what you did?

I need to create a key with multiple parts and would like to encrypt it without any control chars. The key would need to be entered into an application to license the software.

Thanks for your help,

Rick

Hi Rick,

I am not sure why you need to encrypt the key, but I can imagine that your key generation code may produce a key with undesirable characters.

You could use Base64 encoding to ensure that your generated key only uses a sane set of characters. Of course, that will also increase the count of characters that needs to be entered.

Cheers,

Brian

Hi Brian, 

You are correct, I shouldn't have used that term. I do want to hide the actual characters in some kind of way. Maybe converting the text to Hex.

Any ideas?

Yes

HI All,

I found that OpenSSL will do the job.

Thanks,

Rick
