The OCSBC hashes passwords using a randomly generated salt with 65532 iterations of the SHA-512 algorithm. Enabling SHA-2 Password Hashing Passwords are changed with the secret login command. All newly set passwords are hashed with SHA-2, the SHA-1 hash is removed, and thereafter the OCSBC ...
$6$ is 512-bit Secure Hash Algorithm (SHA-512) $y$ (or $7$) is yescrypt none of the above means DES Critically, as of this writing, yescrypt with its contest entry yescrypt v2 and current specification, is widely-adopted and the default password hashing scheme for many recent versions...

By default, the grub-crypt command encrypts the password using SHA-512 algorithm. You can also encrypt the password either using SHA-256 or MD5 alrogithms as shown below. # grub-crypt --sha-256 # grub-crypt --md5 You can also use md5crypt to encrypt the password. In that case, you...
MFcrypt is the key-derivation function of the scheme. It applies the mixing function SMix and the PBKDF2 with an HMAC that uses the SHA-256 hash function. Figure 4 illustrates the internal software components of Scrypt. Figure 4. Scrypt software components. At first, MFcrypt parses the ...
SHA-256, for instance, can be very efficiently implemented on a GPU, since it uses only 32-bit logic and arithmetic operations that GPU are very good at. (...) Bcrypt happens to heavily rely on accesses to a table which is constantly altered throughout the algorithm execution. This is ...
vulnerable to collision attacks, which means that two different messages can be found that produce the same hash value. Because of this vulnerability, MD5 is no longer considered a secure hashing algorithm for cryptographic purposes, and other algorithms such as SHA-256 and SHA-3 are recommended ...
SSHA256, SSHA384, SSHA512: Salted versions of the three SHA-2 algorithms. SMD5: Salted MD5. This is similar to MD5, but is generated by using a random salt with the password. UNIX Crypt: The UNIX hashing algorithm None: Passwords are stored in clear text. See Managing Hashing Scheme...
