    Hi Karl-WE, I think there might be a misunderstanding about what "P521" represents in that key storage provider. P521 (along with P256 and P384) are elliptic curves that have been defined by the U.S. National Institute of Standards and Technology (NIST) in FIPS 186-4, section D.1.2.5, as well as in SP 800-186, section 3.2.1.5.  "P521" is actually the correct name to represent this elliptic curve in that key storage provider.

Great to learn about that Troy! I thought it is like cipher, hash lenght and 256 would be followed by a multiple of these.
