WebMar 12, 2024 · For x25519, can multiple PK's resolve to a single SK, or is there ever only one unique PK-SK pair? If I wasn't mistaken, there can be atmost 2 PK corresponding to 1 SK in x25519, depending on whether the implicit y-coordinate is internally positive or negative. As for ECDH on the other hand, the mapping is 1:1. WebOct 8, 2024 · No. X25519 isn't a curve, it's an Elliptic-Curve Diffie-Hellman (ECDH) protocol using the x coordinate of the curve Curve25519. Ed25519 is an Edwards Digital Signature Algorithm using a curve which is birationally equivalent to Curve25519. Is X25519 used by ECDSA? No. It's not a curve, it's an ECDH protocol.
