96 * This converts an ASN1 INTEGER into its content encoding.-
97 * The internal representation is an ASN1_STRING whose data is a big endian-
98 * representation of the value, ignoring the sign. The sign is determined by-
99 * the type: V_ASN1_INTEGER for positive and V_ASN1_NEG_INTEGER for negative.-
100 *-
101 * Positive integers are no problem: they are almost the same as the DER-
102 * encoding, except if the first byte is >= 0x80 we need to add a zero pad.-
103 *-
104 * Negative integers are a bit trickier...-
105 * The DER representation of negative integers is in 2s complement form.-
106 * The internal form is converted by complementing each octet and finally-
107 * adding one to the result. This can be done less messily with a little trick.-
108 * If the internal form has trailing zeroes then they will become FF by the-
109 * complement and 0 by the add one (due to carry) so just copy as many trailing-
110 * zeros to the destination as there are in the source. The carry will add one-
111 * to the last none zero octet: so complement this octet and add one and finally-
112 * complement any left over until you get to the start of the string.-
113 *-
114 * Padding is a little trickier too. If the first bytes is > 0x80 then we pad-
115 * with 0xff. However if the first byte is 0x80 and one of the following bytes-
116 * is non-zero we pad with 0xff. The reason for this distinction is that 0x80-
117 * followed by optional zeros isn't padded.-
