CVE-2022-29245 Weak private key generation in SSH.NET

SSH.NET is a Secure Shell SSH library for .NET. In versions 2020.0.0 and 2020.0.1, during an X25519 key exchange, the client’s private key is generated with System.Random. System.Random is not a cryptographically secure random number generator, it must therefore not be used for cryptographic...

SSH.NET 安全特征问题漏洞

SSH.NET is an SSH library for .NET optimized for parallelism. A security signature issue vulnerability exists in SSH.NET versions 2020.0.0 and 2020.0.1, which stems from a client's private key being generated during an X25519 key exchange using System.Random. System.Random is not a...

Is X25519 Associative? Sometimes!

X25519 is a simple Elliptic Curve Diffie-Hellman ECDH function: it takes a scalar a fancy name for an integer1 and an elliptic curve point, and it multiplies the elliptic curve point by the scalar. Point additions and multiplications work modulo the order of the point, just like hours on a watch...

Using Ed25519 signing keys for encryption

@Benjojo12 and I are building an encryption tool that will also support SSH keys as recipients, because everyone effectively already publishes their SSH public keys on GitHub. For RSA keys, this is dangerous but straightforward: a PKCS1 v1.5 signing key is the same as an OAEP encryption key...
