WebDec 17, 2024 · A complete DSA key is made up of 5 values: p, q, g, x, and y. p, q, g, and y are all public values. The /public_key endpoint on the server gives these values and can be used to verify that a given signature is valid. The private value, x, is what we need. A DSA signature is normally computed as follows First pick a k where 0 < k < q
