password-hashing - Password hashing code.

•    PHP

---

This repository contains peer-reviewed libraries for password storage in PHP, C#, Ruby, and Java. Passwords are "hashed" with PBKDF2 (64,000 iterations of SHA1 by default) using a cryptographically-random salt. The implementations are compatible with each other, so you can, for instance, create a hash in PHP and then verify it in C#. This code uses the PBKDF2 algorithm to protect passwords. Better technologies for protecting passwords exist today, like bcrypt, scrypt, or Argon2. Before using this code, you should try to find a well-reviewed and carefully-made implementation of one of those algorithms for the language that you are using. These algorithms are "memory hard," meaning that they don't just need a lot of CPU power to compute, they also require a lot of memory (unlike PBKDF2). By using a memory hard algorithm, your passwords will be better protected.

bcrypt - Modern password hashing for your software and your servers

•    C

---

Note that bcrypt should build very easily on Linux provided you have a C compiler, headers for Python (if you're not using pypy), and headers for the libffi libraries available on your system. While bcrypt remains a good choice for password storage depending on your specific use case you may also want to consider using scrypt (either via standard library or cryptography) or argon2id via argon2_cffi.

scrypt - A Ruby gem with native C extension for the scrypt password hashing algorithm.

•    C

---

The scrypt key derivation function is designed to be far more secure against hardware brute-force attacks than alternative functions such as PBKDF2 or bcrypt. The designers of scrypt estimate that on modern (2009) hardware, if 5 seconds are spent computing a derived key, the cost of a hardware brute-force attack against scrypt is roughly 4000 times greater than the cost of a similar attack against bcrypt (to find the same password), and 20000 times greater than a similar attack against PBKDF2.

The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes.

credential - Easy password hashing and verification in Node

•    Javascript

---

Easy password hashing and verification in Node. Protects against brute force, rainbow tables, and timing attacks.Employs cryptographically secure, per password salts to prevent rainbow table attacks. Key stretching is used to make brute force attacks impractical. A constant time verification check prevents variable response time attacks.

ring - Safe, fast, small crypto using Rust

•    Rust

---

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.

masterkey - secure interactive password manager with xchacha20poly1305, argon2id, and Go

•    Go

---

masterkey is a simple, secure password manager written in Go. It uses xchacha20poly1305 for authenticated encryption and argon2id for key derivation. It stores credentials given a location, where each credential is represented by a Username and a Password. Locations, Usernames, and Passwords are always encrypted using a argon2id key derived from the input passphrase. Unlike password-store and a few other password managers, an attacker with access to the encrypted database can not discern exactly how many passwords are stored, the labels (locations) for the passwords, or the usernames associated with the passwords. Now create your vault, in this example we'll create it at ./vault.db. New vaults are created using the -new flag, existing vaults can be opened by simplly omitting the -new flag.

Scrypt for Node/IO is a native node/io C++ wrapper for Colin Percival's scrypt cryptographic hash utility. As should be the case with any security tool, this library should be scrutinized by anyone using it. If you find or suspect an issue with the code- please bring it to my attention and I'll spend some time trying to make sure that this tool is as secure as possible.
