  *
  * hex_to_bin() converts one hex digit to its actual value or -1 in case of bad
  * input.
+ *
+ * This function is used to load cryptographic keys, so it is coded in such a
+ * way that there are no conditions or memory accesses that depend on data.
+ *
+ * Explanation of the logic:
+ * (ch - '9' - 1) is negative if ch <= '9'
+ * ('0' - 1 - ch) is negative if ch >= '0'
+ * we "and" these two values, so the result is negative if ch is in the range
+ *	'0' ... '9'
+ * we are only interested in the sign, so we do a shift ">> 8"; note that right
+ *	shift of a negative value is implementation-defined, so we cast the
+ *	value to (unsigned) before the shift --- we have 0xffffff if ch is in
+ *	the range '0' ... '9', 0 otherwise
+ * we "and" this value with (ch - '0' + 1) --- we have a value 1 ... 10 if ch is
+ *	in the range '0' ... '9', 0 otherwise
+ * we add this value to -1 --- we have a value 0 ... 9 if ch is in the range '0'
+ *	... '9', -1 otherwise
+ * the next line is similar to the previous one, but we need to decode both
+ *	uppercase and lowercase letters, so we use (ch & 0xdf), which converts
+ *	lowercase to uppercase
