SwiftSPHINCS is a Swift implementation of NIST FIPS 205: Stateless Hash-Based Digital Signature Standard, August 13, 2024.
SwiftSPHINCS functionality:
- Support for the 12 parameter sets defined in the standard
- Create public and secret keys
- Sign messages - deterministically or randomized, pure or pre-hashed, with or without context.
- Verify signatures, pure or pre-hashed, with or without context
- Store keys in their PEM encoded ASN1 representation
- Restore keys from their PEM encoded ASN1 representation
SwiftSPHINCS requires Swift 5.0. It also requires that the Int and UInt types be 64 bit types.
Its documentation is build with the DocC plugin and published on GitHub Pages at this location:
https://leif-ibsen.github.io/SwiftSPHINCS/documentation/swiftsphincs
The documentation is also available in the SwiftSPHINCS.doccarchive file.
The KAT test vectors come from NIST ACVP-server version 1.1.0.38 to comply with the final specification.
