So I went through my
/etc/shadow file in Linux and discovered that my passwords were stored in SHA-512-based crypt ('sha512crypt') mode, so SHA-512. But why? I mean SHA-512 is not even a secure password hashing function. Why not bcrypt or Argon2 or scrypt ....
And how much iteration does this hash even have?
$2$ "Blowfish" mean bcrypt ? And if yes, then why do they use the name of the block cipher?
