 # VanitySearch
 
-VanitySearch is a bitcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (*VanitySeacrh.exe -s "My PassPhrase" 1MyPrefix*).\
+VanitySearch is a bitcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (*VanitySeacrh.exe -s "My PassPhrase" 1MyPrefix*). You can also use *VanitySeacrh.exe -ps "My PassPhrase"* which will add a crypto secure seed to your passphrase.\
 VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
