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).

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?
