Quick question: I'm looking for a simple utility program to be able to decrypt rsa-encrypted data (either base64-encoded or binary attachment) on a Windows workstation.
Scenario: There is a group of operators that will get email alerts with information on user they have to contact. Part of the info is encrypted, and we need them to be able to decrypt that info to reach out to the users. They'd have the corresponding private key, so the idea would be to "paste the private key and the text" or "open the attachment" and get the resulting 1-2 lines of decrypted text.
I know that OpenSSL and some scripting in Perl, or a zillion other options, would get me the data, but that would mean:
- Deploying OpenSSL to the operator's computers
- Deploying ActivePerl (or similar)
- Allowing the operators to open a command prompt on the machine (current security policy disables it)
- Teaching them how to run the script from the command line
Quite a bit of work I'd rather avoid.
I've been googling around, and I've found one million versions of the recipes for
openssl, half a million source code examples, and no "encryption utilities"... So I've decided to ask here in case someone is aware of some (probably obscure) tool that does what I need...
Thanks a lot in advance!!
