Codeigniter 412/18/2023 The key your configuration provides is used to derive two other keys, one forĮncryption and one for authentication. The OpenSSL extension has been a standard part of PHP for a long time.ĬodeIgniter’s OpenSSL handler uses the AES-256-CTR cipher. Encryption Handler Notes OpenSSL Notes This ensures that the length of the transmitted data is constant, and that the server doesn’tĮffortlessly get a copy of the password. A client willing to sendĪ password to a server should hash it instead (even with a single iteration of the hash function). Padding in order to hide the length of a password is not recommended. The more secure implementation of a library. You are advised not to devise your own padding implementation. You can use the Encryption library’s createKey() method. Nor the output of a hashing function, etc. The key should be as random as possible, and it must not be a regular text string, Your encryption key must be as long as the encryption algorithm in use allows.įor AES-256, that’s 256 bits or 32 bytes (characters) long. The AES-256-CTR algorithm, your configured key, and SHA512 HMAC authentication. Default Behavior īy default, the Encryption Library uses the OpenSSL handler. Stronger algorithms of course will be added in the future as theyĪppear and become widely available. If you absolutely need to use them, it is easy to do so via PHP’s MD5 or SHA1 is that they are no longer considered secure enoughĪnd as such, we don’t want to encourage their usage. The reason for not including other popular algorithms, such as driver = 'OpenSSL' // Your CI3's 'encryption_key' $config -> key = hex2bin ( '64c70b0b8d45b80b9eba60b8b3c8a34d0193223d20fea46f8644b848bf7ce67f' ) // Your CI3's 'cipher' and 'mode' $config -> cipher = 'AES-128-CBC' $config -> rawData = false $config -> encryptKeyInfo = 'encryption' $config -> authKeyInfo = 'authentication' $encrypter = Services :: encrypter ( $config, false ) Supported HMAC Authentication Algorithms įor HMAC message authentication, the Encryption library supports The $config variable must beĪn instance of the Config\Encryption class. You can replace the config file’s settings by passing a configuration Whether the cipher-text should be raw ( true) Preferred handler, e.g., OpenSSL or Sodium ( OpenSSL) The example above uses the configuration settings found in app/Config/Encryption.php. encrypt ( $plainText ) // Outputs: This is a plain-text message! echo $encrypter -> decrypt ( $ciphertext ) Īnd that’s it! The Encryption library will do everything necessaryįor the whole process to be cryptographically secure out-of-the-box. (an O-O package built on libsodium) is another possibility. One of the other Cryptography Extensions. Public-key encryption, we suggest you consider direct use of OpenSSL or If you need more capabilities, for example, This is not a full cryptographic solution. The following PHP extensions are currently supported: Using an appropriate PHP cryptographic extension or third-party library may requireĪdditional software to be installed on your server and/or might need to be explicitly The service will instantiate and/or initialize anĮncryption handler to suit your parameters as explained below.Įncryption Service handlers must implement CodeIgniter’s simple EncrypterInterface. The Encryption Service provides two-way symmetric (secret key) data encryption. Should do that through PHP’s Password Hashing extension. Password storage! Passwords must be hashed instead, and you Remove index.DO NOT use this or any other encryption library for.How to apply server-side form validation in Codeigniter 4, and more tutorials of Codeigniter 4.
