What's JavaScript Hashing Libraries?

JavaScript hashing libraries are essential tools for developers who need to generate hash values for data integrity, security, and cryptographic purposes. These libraries provide various hashing algorithms that allow developers to create unique identifiers for data, ensuring that even the slightest change in input results in a completely different hash output. This is particularly useful in applications involving password storage, data verification, and digital signatures. Each library has its own strengths and weaknesses, making it crucial to choose the right one based on specific project requirements.

supported hashes

sha.js currently implements:

  • SHA (SHA-0) -- legacy, do not use in new systems
  • SHA-1 -- legacy, do not use in new systems
  • SHA-224
  • SHA-256
  • SHA-384
  • SHA-512

Not an actual stream

Note, this doesn't actually implement a stream, but wrapping this in a stream is trivial. It does update incrementally, so you can hash things larger than RAM, as it uses a constant amount of memory (except when using base64 or utf8 encoding, see code comments).
