history
Project history and usage
scrypt is both a memory-hard password-based key-derivation function and the name of its reference command-line file-encryption utility.
Project history
Colin Percival originally developed scrypt for the Tarsnap online backup system. The design was presented at BSDCan 2009 as a sequential memory-hard key-derivation function intended to raise the hardware cost of brute-force attacks.
The project also supplies a demonstration command-line encryption utility and reference C implementation. The algorithm was later standardized by the IETF as RFC 7914.
Adoption history
The algorithm moved beyond its original Tarsnap use into the IETF standards process and language ecosystems. The official project page records support in Python's hashlib, Node.js crypto, Go's x/crypto packages, and numerous bindings; it also notes use of a simplified variant by Litecoin.
How it is used
The command uses `scrypt enc` and `scrypt dec` to encrypt or decrypt files, with optional limits for computation time and memory. Developers can also use the included C implementation as a KDF. The documentation cautions consumers to verify successful authenticated decryption before using produced output.
Why package nerds care
scrypt helped make memory hardness a mainstream package-selection concern. Package maintainers encounter the name both as a cryptographic primitive exposed by libraries and as the small reference file-encryption command distributed here.
Timeline
- 2009: Colin Percival presented scrypt at BSDCan and published the original design paper.
- 2016: The IETF published scrypt as RFC 7914.
- 2019: The official utility reached version 1.3.0.
- 2025: The official project published version 1.3.3.
Related projects
- The official documentation compares scrypt with PBKDF2 and bcrypt and lists implementations for Python, Node.js, Go, Ruby, Haskell, and other environments.
