+Summary: The DER encoding of an ASN1 INTEGER must be encoded with a minimum number of octets.
+
+The DER encoding of an ASN1 INTEGER must be encoded with a minimum number
+of octets. The Mono.Security.ASN1Convert.FromUnsignedBigInteger method
+always prepends a null byte when encoding, thereby encoding for example the
+public key exponent 65537 as 0101 instead of 101. 
+
+The solution would be to only prepend a null byte for determinedly negative
+numbers ie where the sign bit is set in the first byte.
