Crypto & Security Tools

Need a test secret, a digest, a UUID, or a peek at a JWT payload while debugging? These helpers run locally so sample credentials are not pasted into a random third-party form. They are for development and inspection - production key material still belongs in your platform KMS and vetted libraries.
