| | MARS |
 | | The document describing MARS, accessible at http://www.research.ibm.com/security/mars.html, notes that "little-endian" conventions, with the "first" byte of a 32-bit word being its least significant byte, are used in the cipher. |
 | | The four bytes of the first word in the block, W0, are used as inputs to the two fixed S-boxes used by this cipher with eight bits of input and 32 bits of output. |
 | | The second word is XORed with the word in S0 chosen by the least significant byte of the first word and then the word in S1 chosen by the third, or second least significant, byte of the first word is added to it. |
