Dear all,

If one encrypts an empty string with RSA (say in a C/Perl/Ruby  
program), and then tries to decrypt it using the command-line  
application rsautl, the decryption output is a zero-length file (as it  
should be) but rsautl also prints: "RSA operation error".

In this specific case it's not an error, it simply is an empty output  
string. Maybe rsautl should print a special warning message for this  
case.

This happens on openssl-0.9.8k on Mac, Linux and Windows XP.

Best,

Dov Murik
