php encrypt password code example

Example 1: php hash password

//hash password
$pass = password_hash($password, PASSWORD_DEFAULT);

//verify password
password_verify($password, $hashed_password); // returns true

Example 2: password hash php

//hash password
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

//verify password
password_verify($password, $hashed_password); // returns true

Example 3: php hash password

/* User's password. */
$password = 'my secret password';

/* Secure password hash. */
$hash = password_hash($password, PASSWORD_DEFAULT);

Example 4: password_hash() php 7

<?php
/**
 * Note that the salt here is randomly generated.
 * Never use a static salt or one that is not randomly generated.
 *
 * For the VAST majority of use-cases, let password_hash generate the salt randomly for you
 */
$options = [
    'cost' => 11,
    'salt' => mcrypt_create_iv(22, MCRYPT_DEV_URANDOM),
];
echo password_hash("rasmuslerdorf", PASSWORD_BCRYPT, $options)."\n";
?>

Example 5: php password encryption and decryption

function encryptPass($password) {
    $sSalt = '20adeb83e85f03cfc84d0fb7e5f4d290';
    $sSalt = substr(hash('sha256', $sSalt, true), 0, 32);
    $method = 'aes-256-cbc';

    $iv = chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0);

    $encrypted = base64_encode(openssl_encrypt($password, $method, $sSalt, OPENSSL_RAW_DATA, $iv));
    return $encrypted;
}

function decryptPass($password) {
    $sSalt = '20adeb83e85f03cfc84d0fb7e5f4d290';
    $sSalt = substr(hash('sha256', $sSalt, true), 0, 32);
    $method = 'aes-256-cbc';

    $iv = chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0);

    $decrypted = openssl_decrypt(base64_decode($password), $method, $sSalt, OPENSSL_RAW_DATA, $iv);
    return $decrypted;
}

Example 6: password encryption php

<?php
  //HASH a password with the default algorithm
  echo password_hash('rasmuslerdorf', PASSWORD_DEFAULT);
?>
