rust-openssl: Deriver::derive and PkeyCtxRef::derive can overflow short buffers on OpenSSL 1.1.1

Deriver::derive and PkeyCtxRef::derive sets len = buf.len and passes it as the in/out length to EVPPKEYderive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extract ignore the incoming keylen, unconditionally writing the full shared secret 32/56/prime-size bytes. A...

Name of the Vulnerable Software and Affected Versions rust-openssl versions 0.9.27 through 0.10.77 Description An issue exists where Deriver::derive and PkeyCtxRef::derive set the len variable to buf.len and pass it as the in/out length to EVP PKEY derive. When using OpenSSL 1.1.x, the X25519,...

Primitive Vector Cipher(PVC): A Hybrid Encryption Scheme Based on the Vector Computational Diffie-Hellman (V-CDH) Problem

This work introduces the Primitive Vector Cipher PVC, a novel hybrid encryption scheme integrating matrix-based cryptography with advanced Diffie-Hellman key exchange. PVC's security is grounded on the established hardness of the Vector Computational Diffie- Hellman V-CDH problem. The two-layered...

The FIPS Compliance of HKDF

HKDF is an HMAC-based key-derivation function specified in RFC 5869. It’s nice and we generally like using it. FIPS Federal Information Processing Standards is used generally as a moniker for the set of standards, recommendations, and guidance published by the U.S. National Institute of Standards...

Avoid The Randomness From The Sky

This is a plea for cryptography specification authors. If your protocol uses randomness, please make it a deterministic function that takes a fixed-size string of random bytes , and publish known-answer tests for it. This whole issue could really be just the paragraph above, but I feel like I nee...
