{"library":"ecdsa-sig-formatter","type":"library","category":null,"description":"Translate ECDSA signatures between ASN.1/DER and JOSE-style concatenation formats. Version 1.0.11 is the latest stable version; the package is rarely updated but widely depended on by libraries like jsonwebtoken. It converts DER-encoded signatures (common in OpenSSL, crypto libraries) to the concatenated r||s format used by JWT/JOSE standards (ES256, ES384, ES512), and vice versa. It handles base64 encoding/decoding and works with Buffer or string input. Implements no crypto logic itself, only format translation.","language":"javascript","status":"maintenance","version":"1.0.11","tags":["javascript","ecdsa","der","asn.1","jwt","jwa","jsonwebtoken","jose","typescript"],"last_verified":"Thu Jun 04","install":[{"cmd":"npm install ecdsa-sig-formatter","imports":["import { derToJose } from 'ecdsa-sig-formatter';","import { joseToDer } from 'ecdsa-sig-formatter';","import * as format from 'ecdsa-sig-formatter';\nformat.derToJose(derSig, 'ES256');"]},{"cmd":"yarn add ecdsa-sig-formatter","imports":[]},{"cmd":"pnpm add ecdsa-sig-formatter","imports":[]}],"homepage":"https://github.com/Brightspace/node-ecdsa-sig-formatter#readme","github":"ssh://git@github.com/Brightspace/node-ecdsa-sig-formatter","docs":null,"changelog":null,"pypi":null,"npm":"ecdsa-sig-formatter","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":null}
