mkpasswd -m sha-512 password -s “22446688”












0















So I have a question on mkpasswd command result, I must use the same word in this to reproduce the same result hashed over and over, but what happens if I left without the -S option this will create a hashed password with a salted random word, so here is my problem:
with -S option.-



password: p4ssw0rd
word: 22446688
output: $6$22446688$kQPZPIx3oZHwJ/l1xteaU5CqM0m7IoglQPFtDwUSMYCUAHkRUAIAfETjvgJmXhwLm4NVI5DHTXYt9d25cnZN3/



RESULT WILL BE ALWAYS THE SAME ****



WITHOUT -S option.-
output:
$6$nLtu32Q.5ZtRwK9x$z51ORpMvbOmxRj2IveXlqZnBZI16Fnvn4HQA7JBAFIPbhTI/gugtq0XCS3bBl80JBTDrROrm9emMpyRaZt0Pv0
RESULT WIL VARY OVER AND OVER AGAIN****



when I use the word over and over the result is the same, when I don't use the word result is different, so my question is if I take for example option without -S option and used for encrypt password how do I guarantee that when enter password will be compared and will be same since I only have password but I don't know the salt word since this was optional and assigned randomly? or it does not matter since the word is stored with the hash of the password and is not required to know it?



any help to understand will be very appreciated!
