Download the PHP package silencenjoyer/jwe without Composer

On this page you can find all versions of the php package silencenjoyer/jwe. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

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 jwe

🔐 silencenjoyer/jwe

Tests codecov Static Analyze Latest Stable Version PHP Version Require

A PHP library for JSON Web Encryption (JWE) as defined in RFC 7516.

Supports symmetric shared-key and asymmetric RSA end-to-end encryption, multiple content encryption algorithms, and both JWE Compact and JSON serialization formats.

Requirements

Installation

Supported algorithms

Role Identifier Class Description
Key encapsulation dir DirectKeyWrapper / DirectKeyUnwrapper Shared symmetric key used directly as CEK
Key encapsulation RSA-OAEP RsaKeyWrapper / RsaKeyUnwrapper CEK encrypted with recipient's RSA public key
Content encryption A256GCM Aes256GcmFactory AES-256 in GCM mode (32-byte CEK)
Content encryption A256CBC-HS512 Aes256CbcFactory AES-256 in CBC mode with HMAC-SHA-512 (64-byte CEK)

Usage

Symmetric encryption (shared secret)

Both parties share the same secret key. The key is used directly as the Content Encryption Key (CEK), so encrypted_key in the JWE token is empty.

RSA end-to-end encryption

The sender encrypts a random CEK with the recipient's public RSA key. Only the holder of the matching private key can recover the CEK and decrypt the content. No shared secret is required.

To generate a key pair:

AutoDecryptor — algorithm-agnostic decryption

AutoDecryptor reads the algorithm identifiers from the JWE protected header at runtime and selects the correct unwrapper and cipher automatically. Register the algorithms you want to support once, then decrypt any compatible token.

If the token uses an algorithm that was not registered, UnsupportedAlgorithmException is thrown.

Serialization formats

The library supports both JWE serialization formats defined in RFC 7516.

Compact serialization — five base64url parts separated by dots, suitable for HTTP headers and URLs:

JSON serialization — a JSON object, easier to inspect and log:
