FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package aes-bridge

AesBridge PHP

AesBridge is a modern, secure, and cross-language AES encryption library. It offers a unified interface for encrypting and decrypting data across multiple programming languages. Supports GCM, CBC, and legacy AES Everywhere modes.

This is the PHP implementation of the core project.
👉 Main repository: https://github.com/mervick/aes-bridge

Features

🔐 AES-256 encryption in GCM (recommended) and CBC modes
🌍 Cross-Platform: Consistent behavior across different languages
📦 Compact binary format or base64 output
✅ HMAC Integrity: CBC mode includes HMAC verification
🔄 Backward Compatible: Supports legacy AES Everywhere format

Requirements

PHP 7.4 or higher
OpenSSL extension

Installation

Basic Usage

API Reference

GCM Mode (recommended)

Gcm::encrypt(data, passphrase)
Encrypts a string using AES-GCM. Returns: base64-encoded string.
Gcm::decrypt(ciphertext, passphrase)
Decrypts a base64-encoded string encrypted with Gcm::encrypt.
Gcm::encryptBin(data, passphrase)
Returns encrypted binary data using AES-GCM.
Gcm::decryptBin(ciphertext, passphrase)
Decrypts binary data encrypted with Gcm::encryptBin.

CBC Mode

Cbc::encrypt(data, passphrase)
Encrypts a string using AES-CBC. HMAC is used for integrity verification.
Returns: base64-encoded string.
Cbc::decrypt(ciphertext, passphrase)
Decrypts a base64-encoded string encrypted with Cbc::encrypt and verifies HMAC.
Cbc::encryptBin(data, passphrase)
Returns encrypted binary data using AES-CBC with HMAC.
Cbc::decryptBin(ciphertext, passphrase)
Decrypts binary data encrypted with Cbc::encryptBin and verifies HMAC.

Legacy Compatibility

⚠️ These functions are kept for backward compatibility only. Their usage is strongly discouraged in new applications.

Legacy::encrypt(data, passphrase)
Encrypts a string in the legacy AES Everywhere format.
Legacy::decrypt(ciphertext, passphrase)
Decrypts a string encrypted in the legacy AES Everywhere format.

Error Handling

All methods throw exceptions for:

Invalid input data
Incorrect passwords
Corrupted ciphertext
HMAC verification failures (CBC mode)
