This template is no longer in use as it results in poor readability. This function verifies whether a password matches a password hash.

Syntax

bool passwordVerify ( string password, string hash[, function callback] )

Required Arguments

  • password: The password to check.
  • hash: A supported hash (see passwordHash)

Optional Arguments

  • callback: providing a callback will run this function asynchronously, the arguments to the callback are the same as the returned values below.

Returns

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.

Example

See passwordHash example.
