Both keys were very popular during long term (1993-2006) because have good API, appropriate security level and lack of researchers attention. HASP4 was replaced with HASP HL that has strong crypto, but still vulnerable to table emulation.
It seems that first solution appears in the middle of 90’s (HASP 3). HASP4 algo was significantly improved, but secure algorithm was restored in 2004 (?) and published year ago.
