Php Encryption
php-encryption is a symmetric encryption library for PHP that provides tools for authenticated encryption and key derivation to ensure data confidentiality and integrity. It functions as a cryptography toolkit that wraps complex primitives into simplified interfaces to prevent common implementation errors.
The library includes a binary-safe ciphertext serializer to maintain data structure during storage and transmission, as well as a password-based key derivation tool that transforms low-entropy passwords into cryptographically strong keys through iterative processes.
The project covers a broad security surface, including the encryption of sensitive application data and local files. It incorporates constant-time comparison logic to prevent timing side-channel attacks and utilizes randomized initialization vectors for every encryption operation.
