@womorg/optio-quia-vero

A lean, zero dependency library to provide a useful base for your project. Checksums, cryptography, codecs, date-times, error-checking-codes, logging, pseudorandom number generation. The tools you need for any project. Secure build pipeline, provenance signed and typed.

CI NPM ver install size deps LoC

Installation

This module is available through NPM. There are no install scripts, decrease your risk by explicitly preventing (--ignore-scripts)

(pnpm|npm) install @womorg/optio-quia-vero --ignore-scripts

To verify provenance:

npm audit signatures

Algorithms

Checksum/Hash

A checksum; can be used to prevent/identify accidental changes. A hash; maps some data to another, often used for hash tables, or to speed up comparison.

Codec

Crypto

Block

CBC or CTR are recommended by Niels Ferguson and Bruce Schneier. ECB should not be used.

Secure Hash

Cryptography hash functions that have the properties:

  • Finding an input string that matches a hash value (pre-image) is hard
  • Finding a pair of messages that generate the same hash value (collision) is hard

Key Derivation Function (KDF)

A cryptographic algorithm that derives one or more secret keys from a secret value. Can be used to stretch keys (make them longer), or obtain a key in a particular format (eg making a key a fixed length)

  • HKDF
  • PBKDF2 pbkdf2_hmac_sha1, pbkdf2_hmac_sha256, pbkdf2_hmac_sha512
Message Authentication Code (MAC)

Also known as an authentication tag, a short piece of information to authenticate a message. Protect integrity, and authenticity.

DateTime

  • Year, Month, Day
  • Hour, Minute, Second, Millisecond, Microsecond
  • DateTimeLocal, DateTimeUtc, DateOnly, TimeOnly
  • Duration, DurationExact
  • DateTime*.lt|lte|eq|gt|gte|neq - Compare two date-times
  • DateTime*.add|sub - Add or subtract Duration|DurationExact from a date-time
  • DateTime*.diff|diffExact - Get the difference between two dates in y/m/d/h/* or d/h/*

Pseudorandom number generators (PRNG)

  • Marsaglia - possible to calculate in your head
  • Middle-Square - in practice flawed since the period is often short and will converge towards the same number or loop after repeated times
  • MSVC
  • RANDU - a famously bad PRNG

RegExp

  • RegExp escape string

RunTime

  • Configuration (including collecting from environment variables)
  • Structured logging
  • Normalize stack entries, and stack traces across engines, with colors
