1. sign with sha1
python2.4 sign.py -k pvkey.pem -o signx.dat toSvr.dat
related openssl cmd:
  openssl dgst -sha -sign pvkey.pem -out signx.dat toSvr.dat

2. sign with sha256
python2.4 sign256.py -k pvkey.pem -o signx.dat toSvr.dat
related openssl cmd:
  openssl dgst -sha256 -sign pvkey.pem -out signx.dat toSvr.dat

3. verify with sha1
python2.4 ver.py -k pubkey.pem -t toSvr.dat signx.dat
related openssl cmd:
  openssl dgst -sha -verify pubkey.pem -signature signx.dat toSvr.dat 

4. verify with sha256
