A disclosed example separates a source data bit stream into at least a high bit stream and a low bit stream, the high bit stream and the low bit stream associated with an entropy band having an entropy designation indicating a level of entropy content, the entropy designation selected from an entropy designation range between a high entropy designation and a low entropy designation; entropy code the high bit stream and the low bit stream separately; create the at least two band entropy coded bit streams; generate a bit mask with a hash, the hash having inputs of at least a strong encryption key and selected data that is from the source data bit stream, the selected data not encrypted during any encryption process; merge the at least two band entropy coded bit streams into a resultant band entropy coded bit stream based on a sequence of at least one indexed value obtained from the bit mask; and at least one of store or share the resultant band entropy coded bit stream in a same file format as the source data bit stream.
