Halite is a high-level, misuse-resistant cryptography library for PHP built on top of libsodium. It simplifies encryption, decryption, digital signatures, and password hashing by handling nonce management and key representation automatically.

Use cases

• encrypt and decrypt files with streaming symmetric or public-key encryption
• sign and verify messages with ed25519 digital signatures
• encrypt data without manually managing nonces
• store secure authenticated HTTP cookies in PHP applications
• hash passwords securely with argon2
• give PHP developers a safe simple alternative to raw libsodium APIs

When to choose

• you need encryption or signatures in PHP and want to avoid common cryptographic mistakes
• you want file encryption with automatic nonce handling
• you prefer a simple high-level API over libsodium's low-level functions
• you need authenticated encrypted cookies out of the box

When to avoid

• your project is not in PHP
• you need cryptographic primitives or protocols not exposed by libsodium
• you require a permissive license and cannot accept MPL-2.0 terms
• you need cross-language interoperability with non-libsodium crypto formats
