MySQL Password Function: A Prudent Choice?

The MySQL PASSWORD() function raises concerns regarding its suitability for application password hashing. While it may offer certain advantages, it's crucial to examine its limitations and potential drawbacks.

According to MySQL documentation, PASSWORD() is exclusively employed by the authentication system within the database and should not be used in external applications. This warning stems from the function's potential to introduce vulnerabilities and security concerns.

Furthermore, respected security experts advise against relying on MD5 and SHA-1 for password hashing as they are susceptible to attacks. Industry best practices recommend utilizing SHA-256 for enhanced security.

While MySQL has implemented a SHA2() function, its availability in production releases remains uncertain. Developers are encouraged to employ hashing and salting mechanisms within their applications and store the hashed result in the database.

Updates:

  • MySQL 5.5.8 incorporated the SHA2() function.
  • MySQL 8.0 eliminated the PASSWORD() function, rendering it obsolete for application passwords.

In conclusion, using MySQL's PASSWORD() function for application password hashing is not recommended due to security concerns and limitations. Alternative methods such as SHA-256-based hashing and salting offer a secure and reliable approach to protect user passwords.
