OpenSSL - ECDSA signature reliability
The snippet code attached shows ECDSA signature test with secp160r1 curve.
* ((|msg|)) a message with length <= 20,
* ((|sig|)) the ECDSA signature of ((|msg|))
* ((|tamp|)), a string,
Then ((|sig|)) can be successfully used to verify any message in the form ((|msg|)) + ((|tamp|))

it took me a while to look into this... I can't find your attachment, would you still happen to have it around? I think I know what you're aiming at, just want to be sure!
