title: How can I validate an ECDSA signature using the signed data, signature and the signer ECDSA public key?
body: <p>In theory it should be possible to validate the signature of a piece of data if in possesion of the public key, signature and data that was signed and the hash algorithm is known. </p>
  
  <p>I have all these components in binary format. Does anybody have an idea about the easiest way to validate this signature? OpenSSL? Python? An example would be great. Can it be done without writing code?</p>
