7.4. Verifying digital signature
The recordings authentication is based on the standard Digital Signature Algorithm
(DSA). For digital signature, two different keys are generally used, one for creating a signa-
ture (private key), and another key for verifying an authentication (public key).
Any digital signature software can be used for verifying a digital signature. To verify the
authenticity of the sound recording by means of Sound Manager select Service->Authen-
ticate. The window shown at Figure 7.4.1 will be displayed.
