They're not the same thing 'cause they're different characters:
hyphen - (ASCII 45) used to indicate that a hyphen should persistently appear, like en- and em-dashes is vertically placed so as to harmonize w/ lowercase text, unless in a range of all caps.
soft hyphen (ISO 8859: 0xAD, Unicode U+00AD) used to indicate an allowable hyphenation point
en-dash – (ASCII 0150 (on a PC), U+2013; – – –) --- used to indicate duration, or certain linguistic forms
em-dash — (ASCII 0151 (on a PC), U+2014; — — —) --- used to indicate a pause / break in thought as well as various other typographic usages
minus − (U+2212; − − −) --- used to indicate subtraction or a negative. Sets higher than minus, en or em dash so as to align w/ lining figures
