Hi Igor,

Below is an extract of my CSF file, but I still have the same fail:

[Header]
Version = 4.2
Hash Algorithm = sha256
Engine Configuration = 0
Certificate Format = X509
Signature Format = CMS
Engine = ANY

[Unlock]
Engine = CAAM
Features = RNG

I tried also the following config:

[Header]
Version = 4.2
Hash Algorithm = sha256
Engine Configuration = 0
Certificate Format = X509
Signature Format = CMS
Engine = CAAM

[Unlock]
Engine = CAAM
Features = RNG

Best Regards
