++ * This function is used to load cryptographic keys, so it is coded in such a

++ *
++ * 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

++ * 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'
