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