In Java 11 a curve25519 built-in implementation was introduced. As I had no idea of this, and only discovered it recently, I was using a library from ...
For the purposes of performing a Diffie-Hellman key agreement with Curve25519, I am generating the following key pair using BouncyCastle 1.68: Usin ...
I have two points ([32]byte) on curve25519. How do I add them (a + b). I obviously can't do it using big.Int, since they aren't numbers but points on ...
I'm trying to implement curve25519 verification with CryptoPP. I tried the libsignal library first, witch shows correct result. Then I tried the same ...
It seems that .NET (Core 3.1) supports custom curves in ECC. So I've defined the Curve25519, and generated key pair by below code: A sample output ...
I'm trying to create Curve25519 keys using the KeyChain on iOS. I am aware of the existence of CryptoKit, unfortunately, that is not available for iOS ...
I am porting some backend/sdk to nodejs/typescript and I came along a blocker, the source uses libsodium function crypto_scalarmult_curve25519() which ...
I am trying to implement the X3DH algorithm from Signal in Go. However, I got stuck on how to sign the Public Signed PreKey. Per the specifications i ...
I am trying to create a shared secret key between Curve25519 (or X25519) asymmetric key pairs using key exchange algorithms just like Diffie Hellman k ...
Using OpenSSL version 1.1 and or later, I'm able to generate a curve25519 key: openssl genpkey -algorithm x25519 This produces a private key of the ...
When we multiply the basepoint of curve25519 with a scalar number, an exception is thrown. How can we take generator, other than basepoint in this ...
I am developing a .NET Core application and need sFTP support including KexAlgorithm curve25519-sha256 cipher. Does the .NET product provide support f ...
i need to implement ecdh with 25519 using openssl. using: fails. using this: seems to work but i have no idea how to export the public key in ...
I know from SSLHandshakeException: Handshake failed on Android N/7.0 and my own experience that this curve is not available in the system crypto lib f ...
I don't know how to input a point at curve25519 using pbc. If not, how can I calculate pairing points at curve25519? Is there any other lib solving ...
How can we generate a Curve25519 key pair from the command line? We have a MacBook Air with Homebrew installed. Should we use OpenSSL or another ...
I'm looking into using curve25519 on a javacard 3.0.4 but I got stuck and I have the following questions: Does javacard 3.0.4 support such a curve? ...
I have cloned git repository https://github.com/thejh/node-curve25519 and next used npm link inside it. I am using this library in suggested way: var ...
The new SQRL authentication scheme relies on Curve Ed25519 encryption developed by Daniel Bernstein. However, in order to start implementing this sche ...
