encrypt password php code example

Example 1: hash a password php

// To hash the password, use
password_hash("MySuperSafePassword!", PASSWORD_DEFAULT)
  
// To compare hash with plain text, use
password_verify("MySuperSafePassword!", $hashed_password)

Example 2: encrypt decrypt php

function encrypt_decrypt($string, $action = 'encrypt')
{
    $encrypt_method = "AES-256-CBC";
    $secret_key = 'AA74CDCC2BBRT935136HH7B63C27'; // user define private key
    $secret_iv = '5fgf5HJ5g27'; // user define secret key
    $key = hash('sha256', $secret_key);
    $iv = substr(hash('sha256', $secret_iv), 0, 16); // sha256 is hash_hmac_algo
    if ($action == 'encrypt') {
        $output = openssl_encrypt($string, $encrypt_method, $key, 0, $iv);
        $output = base64_encode($output);
    } else if ($action == 'decrypt') {
        $output = openssl_decrypt(base64_decode($string), $encrypt_method, $key, 0, $iv);
    }
    return $output;
}
 
echo "Your Encrypted password is = ". $pwd = encrypt_decrypt('spaceo', 'encrypt');
echo "Your Decrypted password is = ". encrypt_decrypt($pwd, 'decrypt');

Example 3: php hash password

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

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

Example 4: 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 5: password encryption php

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

Example 6: php hash password

<?php
/**
 * In this case, we want to increase the default cost for BCRYPT to 12.
 * Note that we also switched to BCRYPT, which will always be 60 characters.
 */
$options = [
    'cost' => 12,
];
echo password_hash("rasmuslerdorf", PASSWORD_BCRYPT, $options);
?>
