Hi all
I am attempting to populate a Google sheet from form submissions (on Mura
CMS on Lucee 4.5.2.018 / Apache Tomcat 7.0.37). To do this I need to create
a JWT and to do that I need to encrypt various bits of data using the
SHA256withRSA algorithm. When I attempt this, however, I get this error:
Algorithm SHA256withRSA not available
Code: 0
Type: java.security.NoSuchAlgorithmException
Algorithm SHA256withRSA not available
at javax.crypto.Mac.getInstance(Mac.java:176):176
…
…
…
I assume I can take this at face value and the algorithm is not available
in Lucee? Is there a list somewhere of the algorithms that are available?
Is there a plan to implement this algorithm? And, for now, what is the best
way of achieving the encryption I need?
Many thanks.–

You’ll need to tap into the Java libraries, I have this function for
signing bits on my system…

Oh, and the list of algorithms available in Java is
here: https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html
- most of it is already implemented, some is not.
After looking at both BC docs, Java docs and what Jedihomer provided, his
is probably the easier solution at the end of the day since it’s already
wrapped in a function for ya 
Nice work BTW Jedihomer.

You can also do this with the bouncy castle JCE provider,
see https://www.bouncycastle.org/specifications.html for the specs,
http://www.bouncycastle.org/wiki/display/JA1/Provider+Installation for
install instructions (use the static method). I’ve not done this with
Lucee, yet, but I’ve done it a hundred times with ACF. Once the provider is
installed you should have access to SHA256withRSA through the native CF
functions (e.g. hmac in this case).
