The conversion of a string to lower case is replacing upper case characters with their lower case counterparts. Within the ASCII table the upper case characters are at a lower index to their lower case counter parts. The offset is 32 (20hex) e.g. ASCII for 'a' is 97 (61 hex) the ASCII code for 'A' is 65 (41 hex).
That means the conversion is simply an addition of 32 (20hex) to the ASCII code in question. ASCII codes which are between 'A' and 'Z' are going to be replaced.
