WebKey and signature-size. As with elliptic-curve cryptography in general, the bit size of the private key believed to be needed for ECDSA is about twice the size of the security level, in bits. For example, at a security level of 80 bits—meaning an attacker requires a maximum of about operations to find the private key—the size of an ECDSA private key would be 160 bits. WebAnother application in public key cryptography is the digital signature. Digital signature schemes can be used for sender authentication .
