This function verifies whether a password matches a password hash.

Note

Using passwordHash is the recommended way of storing passwords.

Caution

It is strongly recommended to use the async version of the function (i.e. provide a callback function). Otherwise, you will experience short freezes due to the slow nature of the bcrypt algorithm

Syntax

bool passwordVerify ( string password, string hash, table options, function callback )
Required Arguments
  • password: The password to check.
  • hash: A supported hash (see passwordHash ). Note that only the prefix $2y$ is supported for type bcrypt (older prefixes can cause security issues).
  • options: advanced options insecureBcrypt: If set to true , you can use the $2a$ prefix for bcrypt hashes as well. It is strongly not recommended to use it though, because the underlying implementation has a bug that leads to such hashes being relatively easy to crack. This bug was fixed for $2y$ .
  • callback: MISSING_PARAM_DESC

Returns

  • bool: value

Returns true if the password matches the hash. Returns false if the password does not match, or if an unknown hash was passed. If a callback was provided, the aforementioned values are arguments to the callback, and this function will always return true .
