Signature Format: ASN.1 sequence of two INTEGER values: r and s, in that order: SEQUENCE ::= { r INTEGER, s INTEGER } http://en.wikipedia.org/wiki/Abstract_Syntax_Notation_One 30 -- tag indicating SEQUENCE xx - length in octets 02 -- tag indicating INTEGER xx - length in octets xxxxxx - valuer and s are always non-negative. Only supports sigs up to about 65530 bytes. See code to fix BER encoding for this before you add a SigType with bigger signatures.
