Look closely at the values you're passing in for each: Ruby: eyJhbGdvcml0aG0iOiJITUFDLVNIQTI1NiIsImV4cGlyZXMiOjEyNzk4MTgwMDAsIm9hdXRoX3Rva2VuIjoiMTIxMTc2NDk3OTEwMTg5fDIuNlBKWkFNTFozOGcxaUZYMXdraUZwZ19fLjM2MDAuMTI3OTgxODAwMC02MjAzMDc1NDJ8UXd5MHVuZEJ2YVlSYnJWcDBFSkN4eGdVRjQ4LiIsInVzZXJfaWQiOiI2MjAzMDc1NDIifQ PHP: eyJhbGdvcml0aG0iOiJITUFDLVNIQTI1NiIsImV4cGlyZXMiOjEyNzk4MTA4MDAsIm9hdXRoX3Rva2VuIjoiMTIxMTc2NDk3OTEwMTg5fDIuNENNcl9UWV9OVnNKTmpSQlNzOGQ1QV9fLjM2MDAuMTI3OTgxMDgw MC02MjAzMDc1NDJ8eFg5QTBLRzRKbnNHNXZmQ2VaSGJpQmNJeE9vLiIsInVzZXJfaWQiOiI2MjAzMDc1 NDIifQ They're identical up to ...EwMTg5fDIuN but then the Ruby version continues with lBKWkFN... while the PHP version continues with ENNcl9... The hash of two different values will be different.
