"WebHashing is a one-way function (i.e., it is impossible to "decrypt" a hash and obtain the original plaintext value). Hashing is appropriate for password validation. Even if an attacker obtains the hashed password, they cannot enter it into an application's password field and log in as the victim. " - Des hashing

Webcrypt is a POSIX C library function. It is typically used to compute the hash of user account passwords. The function outputs a text string which also encodes the salt (usually the first two characters are the salt itself and the rest is the hashed result), and identifies the hash algorithm used (defaulting to the "traditional" one explained below). This output string … WebDec 15, 2024 · It might be worthwhile to mention that the DES password hash algorithm will only store passwords of up to 8 characters, and will ignore the rest. So if the actual password is longer than that, just getting the first 8 characters right will be enough. Even that alone might be reason enough to switch to another, more modern password hashing …
