Subject: Re: ECDSA encryption with OpenSSL

I am still upset with the ECDSA problems.
Here is another one:
The attached code tends to show that ECDSA message signature (using 
secp160r1 curve is only accurate for messages of length below 21 
characters. All trailing chars are ignored, so if a message of 20 
characters is tampered with additional data, signature verification of 
this new message will still succeed.
Any comment on that ?
