Inspired by\nTupleHash, STROBE, Noise Protocol's stateful objects, Merlin transcripts, and Xoodyak's Cyclist mode, Lockstitch\nuses [SHA-256], [AES-128], and [GMAC] to provide 10+ Gb/sec performance on modern processors at a 128-bit security\nlevel.\n\n[SHA-256]: https://doi.org/10.6028/NIST.FIPS.180-4\n\n[AES-128]: https://doi.org/10.6028/NIST.FIPS.197-upd1\n\n[GMAC]: https://doi.org/10.6028/NIST.SP.800-38D\n\n## CAUTION\n\n⚠️ You should not use this. ⚠️\n\nNeither the design nor the implementation of this library have been independently evaluated. The design is documented\nin [`design.md`](design.md); read it and see if the arguments therein are convincing.\n\nIn addition, there is absolutely no guarantee of backwards compatibility.\n\n## Design\n\nA Lockstitch protocol is a stateful object that has five different operations:\n\n* `Init`: Initializes a protocol with a domain separation string.\n* `Mix`: Mixes a piece of data into the protocol's state, making all future outputs dependent on it.\n* `Derive`: Outputs bytes of pseudo-random data dependent on the protocol's state.\n* `Encrypt`/`Decrypt`: Encrypts and decrypts data using the protocol's state as the key.\n* `Seal`/`Open`: Encrypts and decrypts data with authentication using the protocol's state as the\n  key.\n\nUsing these operations, one can construct a wide variety of symmetric-key constructions.\n\n## Additional Information\n\nFor more information on the usage of Lockstitch, see the godoc.\n\nFor more information on the design of Lockstitch, see [`design.md`](design.md).\n\n## License\n\nCopyright © 2026 Coda Hale\n\nDistributed under the Apache License 2.0 or MIT License.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcodahale%2Flockstitch-go","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcodahale%2Flockstitch-go","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcodahale%2Flockstitch-go/lists"}
