Example 50 with ASN1Integer

use of com.mindbright.asn1.ASN1Integer in project identity-credential by google.

the class Util method signatureDerToCose.

/*
     * From RFC 8152 section 8.1 ECDSA:

     * The signature algorithm results in a pair of integers (R, S).  These
     * integers will be the same length as the length of the key used for
     * the signature process.  The signature is encoded by converting the
     * integers into byte strings of the same length as the key size.  The
     * length is rounded up to the nearest byte and is left padded with zero
     * bits to get to the correct length.  The two integers are then
     * concatenated together to form a byte string that is the resulting
     * signature.
