Expand description

ECDSA P-224 signature generation from SHA224 hash.

The message hash * hash - is signed using the secret key * sk - and the ephemeral session key * ek - . The signature is put into * sig - .

  • sig - Generated signature.
  • hash - Input hash.
  • sk - Secret key.
  • ek - Session key.

Returns 0 If * ek - is a valid session key. Returns -1 Otherwise.
