# FrodoKEM in Golang
|
|
Golang implementation of FrodoKEM: a Practical quantum-secure key encapsulation from generic lattices (https://frodokem.org).
|
|
This implementation passes all KAT tests from the reference specification for all defined key sizes (640 / 976 / 1344) and variants (AES / SHAKE).
|
|
|
|
## API
|
|
There is a demo app that uses every method in the API. i.e. methods for listing variants, for creating key pairs,
|
|
encapsulating & dencapsulating kems, auxiliary methods reporting cipher-text length, key-length, variant name, etc.
|
|
You can find it here: [demo.go](mains/demo/demo.go). The built binary will be placed in `bin/demo` (use `make build` to
|
|
generate it).
|
|
|
|
You can also read the documentation using `go doc -all` in this package, or look at [impl.go](impl.go) and
|
|
[types.go](types.go).
|
|
|
|
_Complete usage Snippet:_
|
|
```go
|
|
import frodo "github.com/kuking/go-frodokem"
|
|
|
|
kem := frodo.Frodo640AES()
|
|
pk, sk := kem.Keygen() // public-key, secret-key
|
|
ct, ssEnc, _ := kem.Encapsulate(pk) // cipher-text, shared-secret
|
|
ssDec, _ := kem.Dencapsulate(sk, ct) // recovered shared-secret
|
|
// ssEnc == ssDec
|
|
```
|
|
|
|
For a full key agreement example, see [agreement_test.go](agreement_test.go).
|
|
|
|
#### Note on Concurrency
|
|
This library is stateless. A FrodoKEM struct (as returned by i.e. `frodo.Frodo640AES()`) can be used concurrently.
|
|
Keys are immutable `[]byte` and they can be shared between concurrent goroutines.
