Enigma is a lightweight Ruby gem designed to verify passwords hashed using Firebase's custom scrypt-based algorithm, making it ideal for seamless integrations and migrations involving Firebase authentication systems. It provides a secure, efficient way to compare a user-provided password against a stored hash without exposing sensitive details, ensuring constant-time comparisons to mitigate timing attacks. Key features include: - Full compatibility with Firebase Authentication's password hashing logic, combining scrypt with AES-256-CTR encryption for signing. - Configurable parameters for scrypt (rounds, memory cost), signer keys, and salt separators. - Secure practices using OpenSSL's fixed-length comparisons. - Support for custom logging, with easy integration into Rails or other frameworks. - Minimal dependencies, relying on the 'scrypt' gem alongside Ruby's standard library. A common use case is migrating users from Firebase to systems like Devise in Ruby on Rails. During migration, extract the user's base64-encoded salt and stored hash from Firebase, then use Enigma to verify the input password. If it matches, set the raw password in Devise to generate a new hash, avoiding forced resets and ensuring a smooth transition. Whether for custom auth systems, password audits, or hybrid setups, Enigma simplifies secure verification while prioritizing ease of use.
Ruby C extension wrapping the yescrypt password hashing algorithm. yescrypt is the default password hash in modern Linux distributions (glibc 2.36+). It extends scrypt with pwxform for stronger time-memory tradeoff resistance. Supports YESCRYPT_WORM (scrypt-compatible), YESCRYPT_RW, and YESCRYPT_DEFAULTS flavors.
SessionKeys is a cryptographic tool for the deterministic generation of NaCl compatible Curve25519 encryption and Ed25519 digital signature keys. The strength of the system is rooted in the fact that the keypairs are derived from passing an identifier, such as a username or email address, and a high-entropy passphrase through the SHA256 one-way hash and the scrypt key derivation functions. This means that no private key material need ever be writter to disk or transmitted. The generated keys are deterministic; for any given ID, password, and strength combination the same keys will always be returned.
