  • SwifT's Data Page - hex2passwd
    hex2passwd n 8 s 05 DWA0Anyg Scrambling When using scrambling the tool will look at the seed to introduce some switching in the mapping table Each bit in the seed decides if switching is needed or not The first bit least significant one decides if the two halves of a map need to be switched The second bit decides if the pairwise quarters of a map need to be switched etc For instance a seed of 05 00000101 will result in Seed 00000101 Map ABCDEFGHIJKLMNOPQRSTUVWX 1 MNOPQRSTUVWX ABCDEFGHIJKL 0 MNOPQR STUVWX ABCDEF GHIJKL 1 PQR MNO VWX STU DEF ABC JKL GHI 0 0 Character Maps A character map contains the list of characters you want to use for your password generation A map must be at least 16 characters wide and always a power of 2 so 16 32 64 128 256 You can create maps with the same character occurring multiple times if you want although this renders the password a little less secure as some characters then have a higher chance of occurring inside the password If you want to use a set of characters with different length I recommend introducing a different character as a non character For instance if you want a password to contain only numbers 0 9 you can use a map 0123456789 and discard the periods in your password echo passwd sha1sum hex2passwd n 10 m 0123456789 3 232833 2 With this example your resulting password would then be 32328332 Why hex2passwd Password Lists You can use hex2passwd to substitute a password list file for all your favorite sites For instance you devise a mnemonic for your passwords such as domainname username sequence decide upon a seed say 14 and charactermap thequickbrownfoxjumpedoverthelazydogbutgotkilledbymockingbirdies Now your password list file just contains the sites with
