| // Package daead provides implementations of the DeterministicAEAD primitive. |
| // |
| // Unlike AEAD, implementations of this interface are not semantically secure, because |
| // encrypting the same plaintex always yields the same ciphertext. |
| // |
| // Example: |
| // |
| // package main |
| // |
| // import ( |
| // "fmt" |
| // |
| // "github.com/google/tink/go/daead" |
| // "github.com/google/tink/go/keyset" |
| // ) |
| // |
| // func main() { |
| // |
| // kh, err := keyset.NewHandle(daead.AESSIVKeyTemplate()) |
| // if err != nil { |
| // // handle the error |
| // } |
| // |
| // d := daead.New(kh) |
| // |
| // ct1 , err := d.EncryptDeterministically([]byte("this data needs to be encrypted"), []byte("additional data")) |
| // if err != nil { |
| // // handle error |
| // } |
| // |
| // pt , err := d.DecryptDeterministically(ct, []byte("additional data")) |
| // if err != nil { |
| // // handle error |
| // } |
| // |
| // ct2 , err := d.EncryptDeterministically([]byte("this data needs to be encrypted"), []byte("additional data")) |
| // if err != nil { |
| // // handle error |
| // } |
| // |
| // // ct1 will be equal to ct2 |
| // |
| // } |
