Pevensie/jargon

Jargon is an Erlang library that provides Argon2 password hashing and verification capabilities. It implements these functions using Native Implemented Functions (NIFs) to interface with a C-based Argon2 implementation, supporting multiple algorithm variants and configurable security parameters. The system is designed for cross-platform compatibility, including support for Windows, Linux, macOS, and FreeBSD.

This change introduces the Jargon library for Erlang, providing modern Argon2 password hashing capabilities. The \jargon\ module exposes \hash/7\ and \verify/2\ functions, allowing users to hash passwords with configurable time, memory, and parallelism costs using Argon2d, Argon2i, or Argon2id algorithms, and to verify passwords against existing hashes. The library is implemented via NIFs (Native Implemented Functions) loading a C-based Argon2 implementation, and includes comprehensive error handling that maps internal C error codes to Erlang atoms for debugging.

src · high confidence

This entry introduces the Jargon library, a modern Argon2 password hashing implementation for Erlang. The release includes full build configuration via rebar3 and a Makefile, enabling compilation on Linux, macOS, FreeBSD, and Windows (via MSYS2). The library exposes functions for hashing and verifying passwords, with platform-specific native artifacts (DLL on Windows, SO on Unix) generated during the build process.

(repo-wide) · high confidence

This change introduces the initial C source files required to build the Jargon NIF library, specifically adding a Makefile and the \jargon.c\ implementation. The Makefile now detects Windows environments (MSYS2) and configures the compiler and path conversions accordingly, enabling the library to be built on Windows in addition to Linux, macOS, and FreeBSD. The \jargon.c\ file implements the Erlang NIF functions \hash\_nif\ and \verify\_nif\ which interface with the Argon2 library to provide password hashing and verification capabilities.

_c\src · high confidence

Added a new test suite (jargon\_tests) that verifies the jargon module's ability to hash and verify passwords using argon2d, argon2i, and argon2id algorithms, as well as tests for error handling with invalid algorithms and insufficient salt lengths.
