What Hex to Base64 actually does to your file
Hex is read in byte pairs, so a string with an odd number of digits is completed with a leading zero rather than refused - if that shifts every value by half a byte, the input was missing a character. Base64 output ends with = padding; keep it, since dropping the padding changes the decoded length on the receiving side.
