In the second part, I’ll take advantage of incorrect usage to forge signatures.\n\nIn this problem set, I will build a hash-based signature system: https://en.wikipedia.org/wiki/Lamport_signature\n\nImplement the `genRandomNum()`, `genPublicKey()` functions in nodejs. `sign()` and `verify()` functions as well.\n\nHint: I will need to look at the bits in each byte in a hash. I can use bit operators in order to do so.\n\nhttps://mrnazu.medium.com/lamport-signature-with-hash-based-signature-schemes-problem-set-11c09aa1e740","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmrnazu%2Flambert-signatures","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmrnazu%2Flambert-signatures","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmrnazu%2Flambert-signatures/lists"}
