Comparison of cryptography libraries

Bernstein has since proposed that the name Curve25519 be used comparison of cryptography libraries the underlying curve, and the name X25519 for the DH function. This base point has order .

Montgomery ladder for ECDH, using only XZ coordinates. Curve25519 is constructed such that it avoids many potential implementation pitfalls. By design, it is immune to timing attacks and it accepts any 32-byte string as a valid public key and does not require validation. The curve is birationally equivalent to a twisted Edwards curve used in Ed25519 signature scheme. Curve25519 was first released by Daniel J.

Bernstein in 2005, but interest increased considerably after 2013 when it was discovered that the NSA had implemented a backdoor into Dual_EC_DRBG. I no longer trust the constants. I believe the NSA has manipulated them through their relationships with industry. Since then, Curve25519 has become the de facto alternative to P-256, and is used in a wide variety of applications. Starting in 2014, OpenSSH defaults to Curve25519-based ECDH.

In 2017, NIST announced that Curve25519 and Curve448 would be added to Special Publication 800-186, which specifies approved elliptic curves for use by the US Federal Government. Both are described in RFC 7748. Exclusive key exchange in OpenSSH 6. A state-of-the-art Diffie-Hellman function by Daniel J.
