CVE-2021-20305

A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions GOST DSA, EDDSA & ECDSA result in the Elliptic Curve Cryptography point ECC multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allow...

CVE-2021-20305

CVE-2021-20305 affects Nettle prior to 3.7.2 where signature verification (GOST DSA, EDDSA, ECDSA) calls ECC multiply with out-of-range scalars, potentially producing incorrect results and allowing an attacker to force an invalid signature (leading to assertion failure or validation issues). Docu...

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...
