Halite is a high-level cryptography interface that relies on libsodium for all of its underlying cryptography operations. Halite was created by Paragon Initiative Enterprises as a result of our continued efforts to improve the ecosystem and make cryptography in PHP safer and easier to implement.
ring is focused on the implementation, testing, and optimization of a core set of cryptographic operations exposed via an easy-to-use (and hard-to-misuse) API. ring exposes a Rust API and is written in a hybrid of Rust, C, and assembly language. ring is focused on general-purpose cryptography. WebPKI X.509 certificate validation is done in the webpki project, which is built on top of ring. Also, multiple groups are working on implementations of cryptographic protocols like TLS, SSH, and DNSSEC on top of ring.
Minisign is a dead simple tool to sign files and verify signatures. Minisign uses the EdDSA signature system, and deterministic signature schemes are fragile against fault attacks. However, conducting these requires physical access or the attacker having access to the same physical host.
Kryptor is a simple, modern, and secure encryption tool. It is a portable, cross-platform command line tool that makes use of modern and secure cryptographic algorithms. It aims to be a mixture of age and Minisign in terms of functionality to provide a simple, user friendly alternative to GPG.
Convert Ed25519 signing key pair into Curve25519 key pair suitable for Diffie-Hellman key exchange. This means that by exchanging only 32-byte Ed25519 public keys users can both sign and encrypt with NaCl.Note that there's currently no proof that this is safe to do. It is safer to share both Ed25519 and Curve25519 public keys (their concatenation is 64 bytes long).
Setting up elliptic curve keys and signing properly for BEP44 can be tricky, especially since bittorrent uses the more obscure supercop/ref10 instead of sodium/nacl ed25519 key formatting.Sign a buffer or string value with the private key.
Regenerable ed25519 keys for OpenSSH and OpenPGP. Passphrase Identity allows you to deterministically generate ed25519 key pairs (signing keys) for OpenSSH and OpenPGP from a set of parameters. This allows you to (re)generate your key pair on a computer which, for example, lacks persistent storage - it derives an "identity" from a passphrase.
This package implements minimal bindings to the ed25519 signature scheme. It's designed to be small, with no dependencies, and fast. It also comes with extensive guidelines and detailed documentation. It should be relatively easy to both depend on directly with Cabal or even copy into any projects that need it directly. For full details (including notes on the underlying implementation), check out the docs.
Ed25519 digital signature algorithm is described in RFC8032. This repository aims to provide modularized implementation of this algorithm. This repository offers at least two different C implementations for every module. Every implementation is tested and can be replaced with other at link-time. New implementations can be added as well.
