| // Package signature provides implementations of the Signer and Verifier primitives. |
| // To sign data using Tink you can use ECDSA or ED25519 key templates. |
| // Example: |
| // |
| // package main |
| // |
| // import ( |
| // "fmt" |
| // |
| // "github.com/google/tink/go/signature" |
| // "github.com/google/tink/go/keyset" |
| // ) |
| // |
| // func main() { |
| // |
| // kh, err := keyset.NewHandle(signature.ECDSAP256KeyTemplate()) // other key templates can also be used |
| // if err != nil { |
| // // handle the error |
| // } |
| // |
| // s := signature.NewSigner(kh) |
| // |
| // a , err := s.Sign([]byte("this data needs to be signed")) |
| // if err != nil { |
| // // handle error |
| // } |
| // |
| // v := signature.NewVerifier(kh) |
| // |
| // if err := v.Verify(a, []byte("this data needs to be signed")); err != nil { |
| // // handle error |
| // } |
| // } |
