Curve25519 option is missing???

[LanceHaverkamp]

Curve25519 option is missing, looked in forms & bug reports for "Curve25519", but not seeing anyone reporting, or asking about this, so here goes:

-------------------------------

So as you see, the elliptic curve options start numbering with 2). But option 1) should be Curve25519

What's going on here?

It is available if one selects (10) ECC (sign only).

Upon selectgin (9) i believe you will generate two keys the Curve25519 for signing and another one for encryption. From above it seems you are selecting wich algo to use for the encryption key, as Curve25519 is not yet standartised for encryption.
