Introduction:<\/strong> <\/p>\n\n\n\n

In the ever-evolving landscape of web development, security remains a paramount concern. Laravel, a popular PHP framework, provides robust tools for implementing encryption within its models. This blog post aims to explore the complexity of encryption in Laravel models, shedding light on best practices and practical implementation tips. <\/p>\n\n\n\n

Steps:<\/strong> <\/p>\n\n\n\n

    \n
  1. Create a Laravel project named \u201claravel-encryption\u201d<\/li>\n<\/ol>\n\n\n\n

    You can create a Laravel project with below composer command below:\u00a0<\/p>\n\n\n\n

    composer create-project laravel\/ laravel-encryption \u2013prefer-dist\u00a0<\/p>\n\n\n\n

      \n
    1. Create a BaseModel.php in \u201capp\/Models\u201d with following content:\u00a0<\/li>\n<\/ol>\n\n\n\n
      <?php \nnamespace App\\Models; \nuse Illuminate\\Foundation\\Auth\\User as Authenticatable; \nuse Illuminate\\Database\\Eloquent\\Factories\\HasFactory; \nuse Illuminate\\Database\\Eloquent\\Model; \n\nclass BaseModel extends Authenticatable \n{ \n\u202f \u202f use HasFactory; \n\u202f \u202f public function setAttribute($key, $value) \n\u202f \u202f { \n\u202f \u202f \u202f \u202f $encrypt_method = \"XXX-XXX-XXX\"; \n\u202f \u202f \u202f \u202f $encrypt_key = hash('sha256', 'ABC_TEST_STRING_KEY'); \n\u202f \u202f \u202f \u202f $encrypt_iv = substr(hash('sha256', 'ABC_TEST_STRING'), 0, 16); \n\u202f \u202f \u202f \u202f if (in_array($key, $this->encrypt)) { \n\u202f \u202f \u202f \u202f \u202f \u202f $value = base64_encode(openssl_encrypt($value, $encrypt_method, $encrypt_key, 0, $encrypt_iv)); \n\u202f \u202f \u202f \u202f } \n\u202f \u202f \u202f \u202f return parent::setAttribute($key, $value); \n\u202f \u202f } \n\n\n\u202f \u202f public function getAttribute($key) \n\u202f \u202f { \n\u202f \u202f \u202f \u202f $encrypt_method = \"XXX-XXX-XXX\"; \n\u202f \u202f \u202f \u202f $encrypt_key = hash('sha256', 'ABC_TEST_STRING_KEY'); \n\u202f \u202f \u202f \u202f $encrypt_iv = substr(hash('sha256', 'ABC_TEST_STRING'), 0, 16); \n\u202f \u202f \u202f \u202f if (in_array($key, $this->encrypt)) { \n\u202f \u202f \u202f \u202f \u202f \u202f return openssl_decrypt(base64_decode($this->attributes[$key]), $encrypt_method, $encrypt_key, 0, $encrypt_iv); \n\u202f \u202f \u202f \u202f } \n\u202f \u202f \u202f \u202f return parent::getAttribute($key); \n\u202f \u202f } \n<\/code><\/pre>\n\n\n\n
      In the above code snippet, you need to keep your own encryption method in place of XXX-XXX-XXX.\u00a0<\/p>\n\n\n\n
      Also, we need 2 strings named \u201ckey\u201d and \u201csecret\u201d and replace the string \u201cABC_TEST_STRING_KEY\u201d with your actual key and \u201cABC_TEST_STRING\u201d with your secret. This will allow you to encrypt and decrypt your all column data with these strings. So please keep this string in a safe place (.env file).\u00a0<\/p>\n\n\n\n
        \n
      1. Extend app\/Models\/User.php with BaseModel:<\/li>\n<\/ol>\n\n\n\n
        <?php \nnamespace App\\Models; \n\nuse App\\Http\\Middleware\\Authenticate; \nuse Illuminate\\Contracts\\Auth\\MustVerifyEmail; \nuse Illuminate\\Database\\Eloquent\\Factories\\HasFactory; \nuse Illuminate\\Database\\Eloquent\\Model; \nuse Illuminate\\Foundation\\Auth\\User as Authenticatable; \nuse Illuminate\\Notifications\\Notifiable; \nuse Illuminate\\Support\\Facades\\Crypt; \nuse Laravel\\Sanctum\\HasApiTokens; \n\nclass User extends BaseModel \n{ \n\u202f \u202f use HasApiTokens, HasFactory, Notifiable; \n\u202f \u202f \/** \n\u202f \u202f \u202f* The attributes that are mass assignable. \n\u202f \u202f \u202f* \n\u202f \u202f \u202f* @var array<int, string> \n\u202f \u202f \u202f*\/ \n\u202f \u202f protected $fillable = [ \n\u202f \u202f \u202f \u202f 'id', \n\u202f \u202f \u202f \u202f 'name', \n\u202f \u202f \u202f \u202f 'username', \n\u202f \u202f \u202f \u202f 'mobile_number', \n\u202f \u202f \u202f \u202f 'email', \n\u202f \u202f \u202f \u202f 'password', \n\u202f \u202f \u202f \u202f 'profile_photo', \n\u202f \u202f ]; \n\n\u202f \u202f protected $hidden = [ \n\u202f \u202f \u202f \u202f 'password', \n\u202f \u202f ]; \n\n \n\u202f \u202f protected $encrypt = [ \n\u202f \u202f \u202f \u202f 'name', \n\u202f \u202f \u202f \u202f 'username', \n\u202f \u202f \u202f \u202f 'mobile_number', \n\u202f \u202f \u202f \u202f 'email', \n\u202f \u202f ]; <\/code><\/pre>\n\n\n\n
        As mentioned in the above code snippet, we have extended BaseModel over the User model. So whenever we query the User table, we will get all decrypted values and whenever we create any new user all columns will have encrypted values in column data.\u00a0<\/p>\n\n\n\n
        Conclusion:\u00a0<\/strong><\/p>\n\n\n\n
        Laravel offers powerful tools for implementing encryption within models, ensuring the security of sensitive data.
