Making statements based on opinion; back them up with references or personal experience. That's not something that password hashes are designed for quite the opposite: with a proper password hash, the only way to recover the password given the hash is to make a guess and verify it and the better the hashing scheme, the more costly verifying guesses is.

If two or more users have selected the same password, due to this feature, their encrypted passwords will be different. mkpasswd is provided by the expect package but is an totally different utility which is available as expect_mkpasswd on Debian / Ubuntu. One of the first methods for this is was the APR1 function: This gives us 48 bits of salt (as we use a Base-64 format for the salt-and where each Base-64 character represents six bits) and uses 1,000 rounds. Ideally, you would use a different truly random salt for each user. Also if the salt is stored with the password, but when adding the user, I don't specify the salt, how will it know the salt? Everything is better with salt, but because hashing is embarrassingly parallel you can (relatively) cheaply brute-force any SHAXXX on GPU (if you are interested to see for yourself, just google "hashcat" - its free and open source program for "attacking" hashes). rev2023.4.17.43393. Thank you! SHA512 encryption is similar to SHA256, but with 512 bits. Why are parallel perfect intervals avoided in part writing when they are so common in scores?

Now compare the new hash with the hash from the database. The useradd command takes in an encrypted password, but it does not ask for the salt. With the knowledge of the salt value, and the password, it was possible to generate the hash encrypted form. See CrackStation for more details. Well, the "$6" part identifies that it is SHA-512, but when I try to hash with SHA-512, it gives the wrong hashed value. What is the default SHA512 salt used in passwd and for the hash stored in the shadow file? Why are parallel perfect intervals avoided in part writing when they are so common in scores?
