Fastest 4KB JS implementation of secp256k1 signatures and ECDH

gnark-crypto provides elliptic curve and pairing-based cryptography on BN, BLS12, BLS24 and BW6 curves. It also provides various algorithms (algebra, crypto) of particular interest to zero knowledge proof systems.

A free, open-source, robust yet user-friendly, compact and cross-platform tool for OpenPGP encryption. It stands out as an exceptional GUI frontend for the modern GnuPG (gpg).

Crypt::LE - Let's Encrypt / Buypass / ZeroSSL and other ACME-servers client and library in Perl for obtaining free SSL certificates (inc. generating RSA/ECC keys and CSRs). HTTP/DNS verification is supported out of the box, EAB (External Account Binding) supported, easily extended with plugins, easily dockerized.

A tool providing additional ECC protection for optical media (unofficial version)

wolfTPM is a highly portable TPM 2.0 library, designed for embedded use.

Fast, general Elliptic Curve Cryptography library. Supports curves used in Bitcoin, Ethereum and other cryptocurrencies (secp256k1, ed25519, ..)

DEPRECATED. Use noble-curves instead. Fastest JS implementation of BLS12-381.

High performance PAR2 create client for NodeJS

Python implementation of ECC pairing and bn_128 and bls12_381 curve operations

webcrypto-liner is a polyfill that let's down-level User Agents (like IE/Edge) use libraries that depend on WebCrypto. (Keywords: Javascript, WebCrypto, Shim, Polyfill)

A set of cryptographic primitives for building a multi-hop Proxy Re-encryption scheme, known as Transform Encryption.
