RUSTSEC-2016-0005

The rust-crypto crate has not seen a release or GitHub commit since 2016, and its author is unresponsive.

NOTE: The (old) rust-crypto crate (with hyphen) should not be confused with similarly named (new) RustCrypto GitHub Org (without hyphen). The GitHub Org is actively maintained.

We recommend you switch to one of the following crates instead, depending on which algorithms you need:

• dalek-cryptography GitHub Org:
  • Key agreement: x25519-dalek
  • Signature algorithms: ed25519-dalek
• ring:
  • AEAD algorithms: AES-GCM, ChaCha20Poly1305
  • Digest algorithms: SHA-256, SHA-384, SHA-512, SHA-512/256 (legacy: SHA-1)
  • HMAC
  • Key agreement: ECDH (P-256, P-384), X25519
  • Key derivation: HKDF
  • Password hashing: PBKDF2
