Encrypt on mobile

Working on permissions and password protection for Quartam PDF Library, and I have a need for RC4 encryption at 40 bits.
Actually, I do have a working plain LiveCode implementation by now, but the 'encrypt' command can do it too and is much faster.
Here's the rub: I read in the release notes for the mobile versions that "industrial strength encryption" is not supported.
So here's a few questions for the iOS/Android developers on the list:
- does a script with 'the cipherNames' or 'encrypt' in it still work, or does it fail to compile?
- does 'the cipherNames' return empty or does it generate an error?
- does the 'encrypt' command return an error in 'the result' or does it generate an error?
An example of a simple test script:
put "plain text" into tData
put "dakey" into tKey -- 40 bits = 5 bytes
if "rc4-40,40" is among the lines of the cipherNames then
encrypt tData using "rc4-40" with key tKey
if the result is not empty then
answer error the result
answer information "RC4-40 returned:" && it
answer information "RC4-40 not available"
Thanks in advance for the feedback!
