Use Curve255719 for this Encryption

[YT-Advanced]

Hello, look like this Encryptions Algorithm use NIST curve. As I known, in 2013, Bernstein was discovered that the NSA had potentially implemented a backdoor into the P-256 curve based Dual_EC_DRBG algorithm. So I think Curve255719 is better to use on SIDH
