WebOption 2: K1 matches K3 but K2 is different (parity bits ignored). The TDES key is 16 bytes long (concatenation of K1 and K2), to achieve 90 bits of effective security. In this mode, the cipher is also termed 2TDES. Option 3: K1 K2, and K3 all match (parity bits ignored). As result, Triple DES degrades to Single DES.
