11 years ago sorry, I think the files (host.cert and host.key) had some issue from where I had used the earlier keys. Its working with another pair of files with below code. So, closing the issue.

Hi,
I am a non-Flex person but was experimenting the AS3Crypto functionalities with Flex .swf embeded into the SAP backend. I am using the original library v1.3 in my flex project. The Symmetric algorithms provided are working fine, but while I was testing the RSA Asymmetric algorithm along with PEM files, its crashing. Please let me know if I am doing something wrong and how to correct it?
Below is my code used for testing the RSA encryption/decryption. It crashes during decryption saying: "TypeError: Error #1009: Cannot access a property or method of a null object reference."
Code I wrote for testing:
