Function raw_signature_to_mpis 

Source 
fn raw_signature_to_mpis(
    sig_type: SignatureType,
    sig: &[u8],
) -> Result<Vec<Vec<u8>>, Error>
Expand description

Parses raw signature bytes as vector of algorithm-specific multiple precision integers (MPIs).

MPIs (see arbitrary-precision arithmetic) are handled in an algorithm specific way. This function prepares raw signature bytes for technology specific use.

ยงErrors

Returns an error if

  • parsing DER-encoded ECDSA signature fails
  • EdDSA signature is of wrong length
  • the signature type is not supported
