windows - Verifying -sha256 signature using OpenSSL -

maven checksum plugin generated 2 files me:

1. schedule.war
2. schedule.war.sha256

on our windows 2008 r2 production machine have openssl, thought using openssl verify signature against war file. not allowed install other software.

so far got print out on cmd hash of war file not verify.

can me command verify?

this have far:

c:\users\administrator>openssl dgst -sha256 -signature schedule.war.sha256 schedule.war sha256(schedule.war)= 3t4g5h6j7kf72333c2894f2942b7b5871d844b25576f7f6fif8fnf8e8w8e5 

i went with:

openssl dgst -sha256 schedule.war sha256(schedule.war)= 3t4g5h6j7kf72333c2894f2942b7b5871d844b25576f7f6fif8fnf8e8w8e5 

and manually open .sha256 file , compare.
