During the process of password hashing, an additional component, known as a
|
|
"salt," is often integrated to bolster the overall security. This salt, acting
|
|
as a defensive measure, primarily wards off certain types of attacks that
|
|
leverage pre-computed tables to crack passwords.
|
|
|
|
However, potential risks emerge when the salt is deemed insecure. This can occur
|
|
when the salt is consistently the same across all users or when it is too short or predictable.
|
|
In scenarios where users share the same password and salt, their password hashes
|
|
will inevitably mirror each other. Similarly, a short salt heightens the
|
|
probability of multiple users unintentionally having identical salts, which can
|
|
potentially lead to identical password hashes. These identical hashes streamline
|
|
the process for potential attackers to recover clear-text passwords. Thus, the emphasis on
|
|
implementing secure, unique, and sufficiently lengthy salts in password-hashing
|
|
functions is vital.
