  Simple ways to encrypt password in PHP are md5(), sha() and crypt(). We can protect password using it.

  Method 1: Password encryption using md5()

  Below is an example:

  View Code PHP

  1 2 3 4 5 6

  <?php $var = "password"; $enc = md5($var); echo "Original Text - $var"; echo "Encrypted Text - $enc"; ?>

  Output:
  Original Text – password
  Encrypted Text – 5f4dcc3b5aa765d61d8327deb882cf99

  For password, add encrypted password into the database.
  And when login is requested, encrypt user’s entered password and compare it with the one in user’s database.

  Method 2: Password encryption using SHA1()

  Below is an example:

  View Code PHP

  1 2 3 4 5 6

  <?php $var = "password"; $enc = sha1($var); echo "Original Text - $var"; echo "Encrypted Text - $enc"; ?>

  Output:
  Original Text – password
  Encrypted Text – 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8

  For password, add encrypted password into the database.
  And when login is requested, encrypt user’s entered password and compare it with the one in user’s database.

  Method 3: Password encryption using crypt()

  Below is an example:

  View Code PHP

  1 2 3 4 5 6

  <?php $var = "This is test"; $enc = crypt($var); //salt be automatically generated echo "Original Text - $var"; echo "Encrypted Text - $enc"; ?>

  Output:
  Original Text – This is test
  Encrypted Text – $1$5K5DEarv$JVOClfGDlGEZQ4IKWqQ8v1

  For password, add encrypted password into the database.
  And when login is requested, use encrypt() as below to validate the password.

  View Code PHP

  1 2 3 4

  <?php if (crypt($input, $password) == $password) { echo "Password verified!"; } ?>

  where $input in user posted password and $password is the encrypted one in database.
