Problem with RSAKey

[Martin Page]

Hi,
         I'm trying to make RSAKey work, running the RSAKeyTest
and having a problem with the testLongText test.... I run it 100
times and it works most of the times, but sometimes it doesn't work ... and I
get this exception:

PKCS#1 unpad: i=0, expected b[i]==2, got b[i]=b
EXCEPTION THROWN: Error: Decrypt error - padding function returned
null!
Error: Decrypt error - padding function returned null!
        at As3Crypto.com.hurlant.crypto.rsa::RSAKey/_decrypt()

I'm working with the src code and the last version.

What can I do?

Thanks.
