    Amazon SNS Message Validator for PHP

    Amazon SNS Message Validator for PHP

    Amazon SNS message validation for PHP

    The Amazon SNS Message Validator for PHP library allows you to validate that incoming HTTP(S) POST messages are valid Amazon SNS notifications. This library is standalone and does not depend on the AWS SDK for PHP or Guzzle; however, it does require PHP 5.4+ and that the OpenSSL PHP extension is installed. Next, you must create an instance of MessageValidator, and then use either the isValid() or validate(), methods to validate the message.

    Sign-In with Ethereum

    Sign-In with Ethereum

    Sign-In with Ethereum library

    ...Already used throughout web3, this is an effort to standardize the method with best practices and to make it easier for web2 services to adopt it. Sign-In with Ethereum describes how Ethereum accounts authenticate with off-chain services by signing a standard message format parameterized by scope, session details, and security mechanisms (e.g., a nonce). The goals of this specification are to provide a self-custodied alternative to centralized identity providers, improve interoperability across off-chain services for Ethereum-based authentication, and provide wallet vendors a consistent machine-readable message format to achieve improved user experiences and consent management.

    EasyJCE

    Provides encryption & password hashing for your app or Hibernate POJOs

    ...A set of Hibernate user types is included to transparently integrate encryption into the data layer in a JPA/Hibernate environment, ensuring data is persisted in its encrypted form while obscuring encryption and decryption logic from application code. EasyJCE supports most algorithms implemented for the JCE, including those provided by third-party encryption service providers. Integrated MAC (Message Authentication Code) support can optionally be used to ensure data integrity and indicate possible data tampering. EasyJCE also provides basic encoding and decoding facilities for transmitting encrypted binary data through mediums which are limited to printable ASCII characters, such as email messages or URL's.
