WebThe following values are accepted: 'binary' (default), the signature is the raw concatenation of r and s. It is defined in the IEEE P.1363 standard. For DSA, the size in bytes of the signature is N/4 bytes (e.g. 64 for N=256 ). For ECDSA, the signature is always twice the length of a point coordinate (e.g. 64 bytes for P-256).
