AI-suggested

Until an official fix is available, users should avoid using affected versions of Crypt::SaltedHash or implement their own cryptographically secure salt generation using a suitable cryptographic random number generator.

Description

Crypt::SaltedHash versions through 0.09 for Perl generate insecure random values for salts. These versions use the built-in rand function, which is predictable and unsuitable for cryptography.
