Thank you. Then there is no problem with my certificate. So how do you create an SPC version 3 request? What will be the requirements for the client?

Hello, The files I received and the sizes are as below. (1) fps_certificate.bin: 2.51KB (2) provisioning_data.bin: 280B Though, I found out that the Apple's sample credential test_fps_certificate_v26.bin was also 1024-bit when I ran the openssl command. openssl x509 -in fps_certificate.bin -text -noout So, I suppose that this is the specification of FairPlay Streaming certificate? The reason why I got in question was that I could only generate SPC v2 request and not SPC v3 on iOS 26.2 or MacOS Sequoia (15.7.1). (Both on Safari browser).
